It is not always the nginx that needs tuning. What about OS?

Have you changed the default file descriptor limits? Something like “Nginx 
stream works very well on 1000~1500 concurrent connections“ might indicate 
you are hitting the default 1024 limit.
While since some kernel versions linux does autotuning still sometimes 
tweaking it a bit helps a lot:   etc ..
