No, I don't use cpu limits and memory limits are plentiful. Besides, the only difference between working and non-working setups were literally single switch `use-http2` in the ingress controller and it was repeatable experience.

That is indeed interesting. I’ve used nginx with grpc (which uses http2) years ago and definitely did not see any such latency issues even at 50k qps
