"The library’s stance, to put it simply, that the juice ain’t worth the squeeze when it comes to low level, compute-bound performance.

Designing software and data structures for performance against unknown use cases on unknown hardware is extremely difficult and the resulting code is much more complicated. Even then, it’s often better to use code written against your actual use case and hardware when performance is that critical.

Things that are off the table might be:

SIMD A highly optimized hash table rewrite Figuring out where inlining or LIKELY causes the compiler to produce better code."

LOL...

Classic vibe coder.
