asm
Go library providing algorithms optimized to leverage the characteristics of modern CPUs (by segmentio)

coregex
Pure Go production-grade regex engine with SIMD optimizations. Up to 3-3000x+ faster than stdlib.
Project mention: We Built the First Pure Go DXIL Generator — Because Optimizing the Wrong Path Wasn't Enough | dev.to | 2026-04-05We weren't afraid of binary formats. Before gogpu, we built scigolib/hdf5 — a Pure Go implementation of HDF5, NASA's hierarchical data format with its own B-tree indices, chunked storage, and compression pipelines. After parsing HDF5 superblocks and fractal heaps in pure Go, LLVM bitcode felt almost... reasonable. We also built coregx/coregex — a regex engine from scratch. Binary formats, state machines, low-level encoding — this is what we do.

go-simdcsv
High-performance SIMD-accelerated CSV parser for Go 1.26+ using simd/archsimd. Drop-in replacement for encoding/csv
Project mention: Show HN: I built a CSV parser to try Go 1.26's new SIMD package | news.ycombinator.com | 2026-01-27 -
Project mention: Aho-Corasick in Go: Multi-Pattern String Matching at 6 GB/s with Zero Allocations | dev.to | 2026-03-18
We built coregx/ahocorasick, a pure Go implementation that achieves over 6 GB/s on a single core with zero heap allocations on the hot path. No cgo, no assembly, no unsafe — just carefully structured Go code and a deep understanding of how modern CPUs access memory.
