We use server as a an aggregator with lots of small income HTTP requests (~1000 RPS). When we reached that number of RPS, http requests started to take randomly longer amount of time (100ms-4 seconds). This is not an issue with our application server because this delays happen even when we try access statics html page via NGINX (
Is it possible to somehow investigate this issue and determine if this is limitation of network card/network infrastructure/bad kernel settings/misconfigured server?
Ready to show any config files.
