msgpack-d has a room for performance improvement.

From above thread, cerealed has similar performance with msgpack-d.
I use modified benchmark script which adds more types.
import std.stdio;
import std.conv;
import std.datetime;
import std.algorithm;
import std.array;
import cerealed;
import msgpack;
struct Struct {
bool b;
int i;
double d;
string s;
string[string] aa;
int[] a;
}
Struct testStruct;
void withCerealed() {
auto enc = Cerealiser();
enc ~= testStruct;
enc.cerealise!((bytes){});
auto s = Decerealiser(enc.bytes).value!Struct;
assert(s == testStruct);
}
void withMsgPack() {
auto bytes = pack(testStruct);
auto s = bytes.unpack!Struct;
assert(s == testStruct);
}
void main() {
testStruct = Struct(true, 5, 3.14, "hi there, nice to meet you!", ["leindex": "levalue"], new int[](20));
auto results = benchmark!(withCerealed, withMsgPack)(1_000_000);
writeln("Cerealed: ", to!Duration(results[0]));
writeln("MsgPack: ", to!Duration(results[1]));
}On my MacBook result:
dmd 2.0.68.0 with -inline -release -boundscheck=off:
Cerealed: 3 secs, 12 ms, 667 μs, and 5 hnsecs
MsgPack: 2 secs, 39 ms, 340 μs, and 2 hnsecs
ldc2-0.15.2-beta2 with -O3 -inline -release:
Cerealed: 2 secs, 205 ms, and 873 μs
MsgPack: 1 sec, 377 ms, 916 μs, and 6 hnsecs
I will check memory usage later.
