This library is based on Go 1.24 - -Replace `import "hash/crc32"` with `import "github.com/klauspost/crc32"` and you are good to go. - -# changes -* 2025: Revived and updated to Go 1.24, with AVX 512 optimizations. - -# performance - -AVX512 are enabled above 1KB input size. This rather high limit is due to AVX512 may be slower to ramp up than -the regular SSE4 implementation for smaller inputs. This is not reflected in the benchmarks below. - -| Benchmark | Old MB/s | New MB/s | Speedup | -|-----------------------------------------------|----------|----------|---------| -| BenchmarkCRC32/poly=IEEE/size=512/align=0-32 | 17996.39 | 17969.94 | 1.00x | -| BenchmarkCRC32/poly=IEEE/size=512/align=1-32 | 18021.48 | 17945.55 | 1.00x | -| BenchmarkCRC32/poly=IEEE/size=1kB/align=0-32 | 19921.70 | 45613.77 | 2.29x | -| BenchmarkCRC32/poly=IEEE/size=1kB/align=1-32 | 19946.60 | 46819.09 | 2.35x | -| BenchmarkCRC32/poly=IEEE/size=4kB/align=0-32 | 21538.65 | 48600.93 | 2.26x | -| BenchmarkCRC32/poly=IEEE/size=4kB/align=1-32 | 21449.20 | 48477.84 | 2.26x | -| BenchmarkCRC32/poly=IEEE/size=32kB/align=0-32 | 21785.49 | 46013.10 | 2.11x | -| BenchmarkCRC32/poly=IEEE/size=32kB/align=1-32 | 21946.47 | 45954.10 | 2.09x | - -cpu: AMD Ryzen 9 9950X 16-Core Processor - -# license - -Standard Go license.
