I’ve been profiling a program that has network latency issues. The baseline latency between client and server is about 0.2ms and overall bandwidth use is low, but when running about ~15k requests/second of size about ~10kb each, latency spikes to about ~75ms.
Looking at `pprof` stack traces and profiles suggest the bottleneck is in net/http.(*http2clientConnPool).getClientConn, waiting for a mutex, and indeed switching to HTTP 1.1 causes latency to drop to 15ms. Is this expected HTTP/2 behavior with high rates of small requests? Are there suggested performance tweaks, or should I just stick to HTTP/1.1?
