[RFC] Optimize Nginx with PGO

[ptr1337]

Nginx is a heavily used webserver.

CachyOS is currently not much known for server usage, but still having a bunch of users, which are using nginx.
As Instrumentation we can use following:

e.g:
/nighthawk_client --rps 15000 --duration 300 --connections 4 --concurrency auto --prefetch-connections -v info http://127.0.0.1:8080

Results from Third Party:

• Release: ~8800 RPS
• Release + PGO: ~9300 RPS

It seems that latency suffers with PGO, according to referenced third party results. It is only one datapoint however and we need to do our own benchmarks.
