EqualFold, IndexFold, ContainsFold, HasPrefixFold, and
HasSuffixFold compare ASCII case-insensitively using the SWAR word
loops: only A..Z/a..z fold, every other byte (including bytes
= 0x80) must match exactly.
HasPrefixFoldandHasSuffixFoldcover the header checks Fiber otherwise spells as an allocation-proneToLower+HasPrefix/HasSuffixpair (authorization schemes such asBearer, content-type prefixes such asmultipart/form-data, suffixes such as+json), and like the other Fold helpers they take the needle as a plain string because call sites pass constant tokens. TheirBenchmark_HasPrefixFold/Benchmark_HasSuffixFoldnumbers are tracked on the benchmark charts and join the catalog above on its next regeneration.
HashFold is the hashing half of a case-insensitive lookup table whose
other half is EqualFold: strings EqualFold reports equal hash equal,
so a table of field or header names can be probed with a key in any case
without first lower-casing a copy of it. It folds each word with
swar.ToLowerWord as it loads it and mixes with wyhash's widening
multiply: keys under eight bytes, as most are, pack into one word and
cost one multiply, with the length in the multiplier so that keys which
pack alike, such as a and aa, stay apart; longer keys take one
multiply per sixteen bytes plus a final one. It takes no seed and is no
defense against collisions planned in advance, so it suits keys of the
program's own, such as the fields of a struct, rather than keys an
attacker picks. Against maphash.String of a strings.ToLower copy,
benchstat over ten runs on an Intel Xeon @ 2.80GHz measured 4.8 ns
against 13.2 ns for a 2-byte key, 4.5 ns against 50.7 ns for a 4-byte
key and 14.7 ns against 184 ns for a 48-byte key, where the copy also
allocates;
go test -run='^$' -bench='^Benchmark_HashFold$' -benchmem -count=10 . > hashfold.txt
followed by benchstat hashfold.txt reproduces that comparison. The
HashFold rows in the amd64 table below, like the table's other rows,
are a single run on the machine its header names.
AppendHTTPDate and FormatHTTPDate write a time in the RFC 9110
preferred HTTP date format (Mon, 02 Jan 2006 15:04:05 GMT,
net/http.TimeFormat), byte-identical to time.Format with that layout
but without walking a layout string: the calendar fields come from one
civil-date conversion of t.Unix() (Hinnant's era arithmetic, instead of
the three abs() walks behind Date, Clock, and Weekday), and are
written into the fixed-width template with two-digit table lookups.
ParseHTTPDate is the reverse: canonical preferred-format input takes a
strict scalar fast path whose validated fields feed time.Unix directly
— the same Time value time.Date builds, minus its normalization pass —
and everything else — the obsolete RFC 850 and asctime forms, unusual
casing, non-GMT zone names, padding — falls back to time.Parse with
net/http.ParseTime semantics, including its errors. Both directions are
pinned to the time package by a day-by-day sweep over the years
0..9999. Date, Last-Modified, and If-Modified-Since handling sit on
every request/response, which makes these the highest-leverage helpers in
this group for Fiber.
AppendQueryEscape/AppendPathEscape and
AppendQueryUnescape/AppendPathUnescape produce byte-identical results
(and, for the unescape pair, identical url.EscapeError values) to their
net/url counterparts, as append-style, allocation-free single passes.
The escape tables are pinned to net/url.shouldEscape by exhaustive
per-byte tests. Unescaping jumps between escape sites with the vectorized
scans (IndexAny2 when + needs rewriting, bytes.IndexByte otherwise)
and copies clean spans wholesale, so route parameters and query values
without escapes — the common case — cost one scan and one copy. Decoding
never grows the input, so dst may be s[:0] on a common backing array
to unescape in place; escaping can grow the input, so there dst must
not alias s.
AppendPathSegmentsEscape covers a whole multi-segment path in one pass:
it escapes every segment as AppendPathEscape does and keeps the /
between them. The output equals escaping each segment and joining with
/, pinned per byte and by fuzzing; net/url's whole-path escaping
differs, as it also leaves ; and , unescaped. The catalog above
measures it against the per-segment loop a caller writes without it; the
other URL benchmarks are still in the amd64 block below.
AppendJSONString appends a value as a double-quoted JSON string,
byte-identical to encoding/json.Marshal of the same string — including
its default HTML escaping (<, >, &), the \ufffd replacement of
invalid UTF-8 bytes, and the U+2028/U+2029 escapes — without any of
Marshal's reflection or allocation. Clean spans are located with a SWAR
scan (the same first-match-mask technique as IndexNonQuotable) and
copied wholesale. This is the building block for hand-rolled JSON hot
paths such as access-log lines and error bodies.
ParseIPv4 and ParseIPv6 parse addresses into netip.Addr, accepting
exactly the strings netip.ParseAddr accepts for the respective family
(pinned by fuzzing) while reporting failure with a bool instead of a
constructed error. Both take strings or byte slices, so fasthttp-style
callers skip the string conversion entirely; remote-address and
trusted-proxy checks parse an IP on every request in Fiber.
CanonicalHeaderKey Title-Cases an HTTP header key exactly like
net/http.CanonicalHeaderKey, including its return-unchanged guard for
keys containing non-token bytes. Already-canonical keys — the common case
on receive paths — are validated in a single table pass and returned
as-is with zero allocations for strings and byte slices alike. Keys that
do need rewriting cost one allocation; note that for the ~40 header names
in the stdlib's interning table the stdlib returns a cached string
without allocating, so this helper's edge there is time, not allocations.
IndexControl returns the index of the first ASCII control byte — a byte
below 0x20 or DEL (0x7F), the RFC 5234 CTL set — and IndexControlExceptTab
is the same scan with HTAB permitted, which is the byte set an RFC 9110
field value may not contain. Both are SWAR first-match scans
(two words per branch, one overlapping word for the tail) over strings or
byte slices; the HTAB exemption is tested only in words that hold a
control byte, so clean input costs the same either way. They never match
bytes >= 0x80, so unlike
strings.IndexFunc(s, unicode.IsControl) they neither decode UTF-8 nor
flag the C1 range hidden inside it. Fiber spells this check by hand in
half a dozen places — header values before they are echoed, request IDs,
Location values, log fields, Basic auth credentials — and each copy is
one of these two calls.
CutByte and LastCutByte are strings.Cut/bytes.Cut for a single
byte separator, around its first or last occurrence, generic over strings
and byte slices. They return the two parts and a found flag exactly like
the stdlib pair (including the ""/nil after-part of a miss), cost one
IndexByte/LastIndexByte, and spare []byte callers the []byte{sep}
needle and the length dispatch inside bytes.Index. CutByte beats
strings.Cut; LastCutByte has no stdlib counterpart, so its row is
measured against a hand-written LastIndexByte split, which it trails by
the cost of the call — its value is the generic []byte support and the
readable spelling. Header parameter splits (;), key=value pairs, and
host/port and name/extension splits are the intended call sites.
SplitHostPort splits host:port, host%zone:port, [host]:port, and
[host%zone]:port with exactly net.SplitHostPort's acceptance rules
(pinned by fuzzing against it), but reports failure with a bool instead
of constructing a *net.AddrError, and accepts byte slices. Valid input
costs the same as the stdlib — the scan is the same three IndexByte
calls — so the win is on the rejection path, where a malformed Host or
Forwarded value no longer costs an allocation, and on []byte input,
which no longer needs a string conversion first.
SplitTrimSeq returns an iterator over the elements of a list separated
by one byte, with ASCII whitespace trimmed from each element and empty
elements skipped — how HTTP list fields such as Accept-Encoding,
Connection, Vary, and Cache-Control are read (RFC 9110 Section
5.6.1: optional whitespace around the commas, empty elements ignored).
It replaces the strings.SplitSeq + TrimSpace + emptiness-check
triplet, locates each separator with a single IndexByte, works on
strings and byte slices alike, and yields subslices without copying. In
an ordinary caller the iterator inlines and allocates nothing, like
strings.SplitSeq; the benchmark ranges inside a helper function for
that reason, because calls made directly inside a b.Loop body are
never inlined and would show the closure allocations instead.
AppendDuration renders a time.Duration exactly as d.String() does —
"72h3m0.5s", "1.5ms", "0s" — into the caller's buffer, with the two-digit
table for the field digits; a value with no fraction, the common case,
never touches the fraction digits. d.String() allocates its result and
fmt.Fprintf("%v", d), which Fiber's logger uses for the latency column,
costs several times more on top; an append-style form makes per-request
duration rendering (access logs, Server-Timing) allocation-free.
FormatUint/FormatInt (and their 32- and 16-bit variants) and
AppendUint/AppendInt render integers eight digits at a time: a value
below 1e8 becomes eight zero-padded digit lanes through a fixed sequence
of multiplies, shifts, and masks (the SWAR inverse of the 8-digit parse
step in ParseInt), so a 64-bit value costs at most three such
conversions and two divisions, all independent of each other, instead of
one dependent divide-and-store per digit; the first significant digit is
found with a trailing-zero count. Values below 100 come from a
precomputed table, and the output is pinned to strconv by a dense sweep
plus every decimal and lane-group boundary. GetMIME in the same spirit
looks up extensions through a hash table keyed by the extension packed
into one lower-cased word with its length in the top lane, so a hit is a
multiply, a shift, and one slot comparison, with no allocation even for
upper-case input.
These helpers were added on an amd64 machine, so like the simd numbers
their benchmarks are recorded separately from the arm64 catalog above and
join it on its next regeneration. The block also carries the current
numbers for the paths reworked on the same machine (integer formatting,
GetMIME, token-sized EqualFold), whose arm64 rows above predate that
work:

The swar package exports the SWAR (SIMD within a register)
building blocks the helpers above are composed from: Load8/Store8,
Broadcast, ZeroLanes, MatchByteMask/MatchRangeMask,
ToLowerWord/ToUpperWord, FirstLane/LastLane, and the WordLen,
Ones, HighBits, and LowSeven constants. They are exported so
downstream packages (Fiber itself, middleware) can fuse their own byte
scans — for example, finding a delimiter while classifying the bytes
before it — without re-deriving the bit tricks. The contracts (unchecked
bounds preconditions, ZeroLanes' approximate mask, the little-endian
lane order) and runnable examples live in the package documentation.
The package benchmarks its primitives against their stdlib counterparts
the same way the helpers above do, measuring the canonical loops composed
from them: Load8/Store8 vs encoding/binary's little-endian
Uint64/PutUint64, a ZeroLanes first-match scan vs
strings.IndexByte, a MatchByteMask+LastLane reverse scan vs
bytes.LastIndexByte, a MatchRangeMask digit scan vs
strings.IndexAny, and an in-place ToLowerWord loop vs
bytes.ToLower. The composed loops are pinned to the stdlib results by a
dedicated test, and the numbers are tracked per commit on the
benchmark charts. Note
that strings.IndexByte is hand-written SIMD assembly and overtakes the
portable SWAR scan on large inputs; the SWAR primitives earn their keep
on short HTTP-sized inputs and on fused scans the stdlib has no single
function for. The package's remaining benchmark, Benchmark_Load8_Fusion,
is an advisory codegen guard rather than an API performance promise, so
it is deliberately not part of the catalog above.
The simd package is the vector-width counterpart to swar: byte
searching and validation whose scan kernels dispatch to AVX2 assembly (four
32-byte vectors per iteration) on amd64 CPUs for inputs of simd.MinLen
(32) bytes or more, and fall back to portable loops built on the swar
primitives everywhere else, so it builds and behaves identically on every
platform.
simd.Accelerated() reports which mode is active. CPU capability detection
uses golang.org/x/sys/cpu,
which also verifies OS support for saving the vector register state.
The AVX2-backed kernels are the multi-needle scans (Memchr2, Memchr3),
the paired-byte scan (MemchrPair), the class scans
(MemchrDigit/MemchrDigitAt, MemchrWord/MemchrNotWord), the ASCII
scans (IsASCII, FirstNonASCII, CountNonASCII), and the substring
search (Memmem), which
prefilters on the needle's rarest bytes (SelectRareBytes, ByteRank)
before verifying candidates — 2-6 byte needles containing two distinct
values are scanned for their two rarest bytes at the exact relative
distance, longer or single-valued needles for the single rarest byte.
Each kernel classifies four 32-byte vectors per iteration. Where the
result is a position or a yes/no, the four masks are combined, so a
128-byte block costs a single VPMOVMSKB and a single branch, and the
scans that report a position re-extract the four masks in address order on
the (rare) hit path. CountNonASCII is the exception — a count cannot be
recovered from a combined mask, so its block loop accumulates per-lane
counts in vector byte lanes (a signed compare against zero and a byte
subtract per vector) and reduces them once at the end, while the
remaining whole vectors are extracted and population-counted; it is the
one kernel gated on POPCNT in addition to AVX2.
One tier is documented explicitly as unaccelerated:
MemchrInTable/MemchrNotInTable are plain
scalar loops, since an arbitrary 256-entry membership test has no cheap
vector form. There is deliberately no single-needle Memchr:
bytes.IndexByte is already vector-accelerated by the Go runtime. Memmem
delegates to bytes.Index for haystacks of up to 64 bytes, where the
stdlib's brute-force vector kernel is level with the paired prefilter
(Benchmark_Memmem_Prefilter forces the prefilter helpers at every size
to keep that measurable); from 65 bytes bytes.Index switches to a loop
anchored on the needle's first byte, and the paired scan takes over.
Needles that take the single rare-byte scan keep a 128-byte routing point,
since that scan is less selective. Both prefilters bail to bytes.Index
after a bounded number of failed candidate verifications, so even
adversarial inputs — a rare byte everywhere plus a long almost-matching
needle — stay within a constant of the stdlib's O(n+m) (see
Benchmark_Memmem_Adversarial). The
package operates on []byte only; the generic top-level helpers IsASCII,
IndexAny2, and IndexAny3 dispatch into it automatically for inputs of
simd.MinLen+ bytes on amd64, which is where the AVX2 kernels overtake the
SWAR word loops (-35% to -88% ns/op at 32-512B in benchstat -count=10
runs; shorter inputs keep the existing SWAR paths).
The kernels are adapted from the coregex
project's simd package (MIT License, Copyright (c) 2025 Andrey Kolkov and
contributors; see simd/LICENSE), with the legacy-SSE
register moves in the kernels replaced by VEX-encoded ones to avoid AVX-SSE
transition stalls, the scalar tail loops replaced by overlapping vector
rescans at the buffer end (a 63-byte scan previously cost ~3.7x a 64-byte
one), the 32-byte main loops replaced by 4x unrolled 128-byte blocks whose
bound is tested once at the bottom against a precomputed limit pointer, the
\w classifier rewritten from three VPMINUB/VPMAXUB clamp-and-compare
range tests into two VPSHUFB nibble-table lookups (with the block test
reduced to one compare over the four raw class values), the digit range
test reduced from two signed compares and a VPANDN to one biased
VPADDB and one compare, FirstNonASCII and CountNonASCII given
kernels of their own (they were SWAR-only, and the count kernel's block
loop accumulates in vector byte lanes rather than extracting and
population-counting every vector's mask), the 128-byte block loops
placed at fixed offsets inside a 32-byte code window so their throughput
no longer depends on where the linker places each kernel, and the
fallbacks reworked around the stdlib and the swar package as described
above.
Against the pre-unrolling kernels, benchstat -count=10 on the machine
below reports -26.6%/-49.7% ns/op for Memchr2 at 512B/4096B,
-17.6%/-34.3% for Memchr3, -13.4%/-24.6% for MemchrPair,
-39.2%/-50.5% for MemchrDigit, -53.5%/-63.7% for MemchrNotWord,
-42.2%/-65.7% for IsASCII, and -13.7%/-27.1% for Memmem, which rides
the paired scan. Those percentages come from benchstat over ten runs of
each side; the single-run table below is a catalog, not a base-vs-head
comparison, so subtracting its rows from an older copy of it will not
reproduce them.
Two bands see no benefit and are worth stating plainly. Inputs below
simd.MinLen never reach the kernels at all. Inputs of 32-127 bytes do
reach them but skip the 128-byte block loop, so they pay its setup with
nothing to amortize it against: across that band benchstat reports the
class scans clearly ahead (MemchrNotWord -8.6% at 32B, -18.4% at 64B;
IsASCII -5.0%/-4.3%), most rows statistically unchanged, and two small
regressions — MemchrDigit +5.6% at 32B and Memchr3 +3.8% at 64B. Read
those small-input figures against the run's own noise floor: the default
legs call unchanged stdlib code, so their movement bounds what a delta of
that size means. They held within 1% in the run quoted here, but a later
run on the same machine drifted up to 17% on those same rows, so anything
under ~10% at 32-64B should be taken as "no measured change" unless its
control legs are quiet.
On the portable side, pinning each unrolled group of words with a reslice
before loading at constant offsets inside it removes the per-load bounds
check that swar.Load8's own reslice otherwise repeats. Measured with
benchstat -count=10 against the same fallbacks, at 32B/512B/4KiB:
IsASCII -28%/-60%/-63%, CountNonASCII -24%/-44%/-44%,
FirstNonASCII -23%/-37%/-43%, Memchr2 -19%/-23%/-25%,
MemchrDigit -7%/-12%/-17%, Memchr3 -8%/-13%/-18%,
MemchrWord -11%/-8%/-11%, MemchrNotWord -5%/-7%/-6%. The tier a group
adds costs one compare on inputs too short to use it, which shows up as
+3% to +10% on some of the 8B fallback rows — a few tenths of a
nanosecond, and only below the length where the group pays for itself.
utils.IsASCII carries the same rework, so the two copies of that scan
stay in step.
Making the counting kernel finish its own sub-vector remainder (rather
than splitting the input in Go and calling the SWAR loop for the tail)
also removed a second non-inlinable call from every whole-vector input:
CountNonASCII at 32B went from 11.3ns — behind its own fallback — to
6.8ns, level with it, and it leads from 64B up.
A later audit pass reworked the kernels and fallbacks once more;
benchstat -count=10 on the machine below, base vs. head, reports:
MemchrDigit-20% at 512B and -27% at 4KiB from the one-add, one-compare range test.MemchrWord-13%/-11% andMemchrNotWord-4%/-10% at 512B/4KiB from comparing the reduced block once instead of every vector, and their SWAR fallbacks -36%/-41% at 32B, -40%/-43% at 64B and -43%/-45% at 512B: 15 ALU operations per word instead of 26, from case-folding the two letter ranges into one test, a one-add underscore test, and a single shared ASCII gate.CountNonASCII-15% at 512B and -41% at 4KiB, with 32B and 64B unchanged: the block loop counts in vector byte lanes (a signed compare against zero and a byte subtract per vector, flushed throughVPSADBWevery 127 blocks) instead of four port-0VPMOVMSKBextractions per block. The remaining whole vectors are still extracted and population-counted, because the vector reduction is a fixed ten-cycle chain that one to three vectors cannot amortize — a first version that used the accumulators for those too was 20% slower at 32-64B.MemchrPair's SWAR fallback -33% at 32B, -41% at 64B, -51% at 512B and -52% at 4KiB, andMemchrPairitself -30% at 32B, where the dispatch routes to that fallback: it now scans two words per branch through pinned three-index windows (no per-load capacity check or pointer clamp) and finishes with one overlapping word instead of a scalar tail. Before, at 32B, it ran no faster than a plain scalar loop.Memmem-62% at 96B: needles that take the paired prefilter are routed through it from 65-byte haystacks, wherebytes.Indexleaves its brute-force vector kernel for a first-byte-anchored loop; 64B and 128B+ are unchanged.
The same pinned-window rework applied to the case-conversion loops in
internal/caseconv, which the strings and bytes packages' ToLower
and ToUpper build on, gives on the same machine -27% to -37% ns/op for
the in-place UnsafeToLower/UnsafeToUpper at 39-64B, -14% to -19% for
the scan-only path that finds nothing to convert, and -5% to -17% for the
allocating conversions, where the allocation dominates. The arm64 catalog
rows above were not regenerated for that change.
Comparing the base and head test binaries also showed the untouched
MemchrPair kernel ~10% slower at 4KiB, purely because the linker had
moved its entry by 32 bytes: on Skylake-derived cores the JCC erratum
mitigation keeps a macro-fused compare-and-branch that crosses or ends on
a 32-byte boundary out of the decoded-uop cache, so the block loop ran
from the legacy decoder. Every block loop is now placed by a BLOCKALIGN
macro at a window offset where all of its fused pairs fit (a few
once-per-call NOPs, visible as +5% on Memchr2 at 512B and nothing at
4KiB), and an amd64 test reads each kernel's code and fails if a later
edit lets a pair straddle a boundary again.
Because the AVX2 kernels only engage on amd64, their benchmark numbers are recorded separately from the arm64 catalog above:
