Hi Team We did CPU profiling by integrating GB java client SDK into our backend service and are making 100 calls to
GB.evalFeature()
per request (assuming in prod we'll run 100 experiments in parallel per request), we observed GB taking too much CPU, we narrowed it down to
MathUtils.fnv1a_32
where it's spending 75% of overall CPU inside GB. As you can see in the attached screenshot, most of the time is being spent inside the hash function. Our overall application CPU increased from 32% to 49% Is there any faster hashing strategy that we can use here?
