How much do amd64 microarchitecture levels help in Go?
Hacker News (AI keywords)6 days agoBenchmarkDaniel Lemire tests Go’s GOAMD64 levels using Roaring Bitmaps on a modern Intel Xeon. v2 brings strong gains where popcnt matters, while v3 adds further speedups in dense bitmap and set-operation workloads through AVX2. v4, despite implying AVX-512 support, shows no meaningful improvement in these benchmarks, likely due to current Go compiler limitations.
sqlite: A CGo-free port of SQLite/SQLite3
Hacker News (AI keywords)7 days agoReleaseThis project provides a CGo-free SQLite/SQLite3 implementation for Go, useful when developers want pure-Go builds and simpler cross-platform deployment. It keeps the familiar SQLite embedded database model while integrating with Go’s database/sql workflow. Recent releases upgraded SQLite, improved text/time scanning performance, added backup progress helpers, and expanded virtual table and sqlite-vec related support.
