Description

Re: #49720

The PR above helped to reduced p50 latency from ~4.09ms down to ~3.89ms. However, it also raised the p99 latency from ~4.77ms to ~7.63ms. The benchmark in the PR probably didn't run long enough to see this taking affect. We should revisit the setup to tweak GC and improve p99 latency.
