Hi,
we recorded more than 30% performance regression on Ubuntu Focal for AWS Graviton instances since Nginx package is not compiled with "-moutline-atomics" cflag for arm64 architecture (337548 rps with default package and 484453 rps using the proposed flag).

As far as I know, only Ubuntu 20.04 is affected by it and we are proposing a fix for it (https:/ /code.launchpad .net/~dipietro- salvatore/ ubuntu/ +source/ nginx/+ git/nginx/ +merge/ 434825).
Set up to reproduce the issue:
- AWS instance: m6g.metal e51092
- AWS ami: ami-0aa916c7b0b
