Ask HN: HN but for Performance

[agencies]

Where do folks keep up with and ask questions about sota performance code (e.g. simd, hashmap tuning, allocators, Dan Lemire, gaming code optimizations, etc.)?

Stackoverflow? Particular forums?

Agner Fog has written manuals regarding software performance. He also has a "links" section on his site which includes some forums: https://www.agner.org/optimize/#links
