Improves per-operation latency in HttpHeaderMap access #9409

jandro996 · 2025-08-22T10:44:38Z

What Does This Do

Optimizes HttpHeaderMap by avoiding % (modulo) in hash index computation when the bucket count is a power of two. It adds:

A powerOfTwo flag to detect powers of two.
A mask = bucketCount - 1 used for fast bitwise index calculation (hash & mask).
Replaces hash % bucketCount with a branch: powerOfTwo ? (hash & mask) : (hash % bucketCount)

Slightly improves per-operation latency in HttpHeaderMap access (~6.5% faster: 21.38 ns → 19.99 ns) with no change in memory allocations (~0 B/op) or GC activity.

Motivation

Using hash & (bucketCount - 1) is significantly faster than % bucketCount when the count is a power of two — a common case in hash-based structures. This improves CPU efficiency without affecting behavior or memory usage.

Additional Notes

Useful in hot paths; no behavioral or memory trade-offs introduced.
