SHA-3 intrinsics have been optimized in this release for x86_64 systems that support AVX-512. The ML-KEM and ML-DSA algorithms extensively use SHA-3. This has resulted in noticeable performance improvements for ML-KEM in key generation, decapsulation, and encapsulation, and ML-DSA key generation, signing, and verification as follows:

- AVX-512
   - `ML-KEM` key generation: +48%
   - `ML-KEM` decapsulation: +47%
   - `ML-KEM` encapsulation: +46%
   - `ML-DSA` key generation: +60%
   - `ML-DSA` signing: +38%
   - `ML-DSA` verification: +74%

The following benchmarks were used to measure performance:

- `micro:org.openjdk.bench.javax.crypto.full.KeyPairGeneratorBench.MLKEM`
- `micro:org.openjdk.bench.javax.crypto.full.KEMBench.MLKEM`
- `micro:org.openjdk.bench.javax.crypto.full.KeyPairGeneratorBench.MLDSA`
- `micro:org.openjdk.bench.javax.crypto.full.SignatureBench.MLDSA`
