comment How to achieve 500K requests per second on my webserver?
Correct. I tried wrk and it gave me 165K requests/sec.

I guess you are right as there are no errors in logs and load, disk activity, memory usage all remain fairly low.

@voretaq7 I agree with you that's why I opened this question to find if its really possible or not. So far I know that bottleneck is with system configs.

Thanks I disabled access logs totally. But same result. This time I carefully noted that disk activity remains zero. 20GB of ram is free and server load is less than 0.5. Looks like bottleneck is server configs.

@ScottPack That answer is perfect for a real life use case, I am testing on the same machine so bottleneck cannot be network. Its either CPU, Memory or IO.

I am benchmarking on the same machine, so its unclear to me why would network limits apply?

I am testing on the same machine, does localhost/test.txt goes through NICs? I will try your suggest and post the results.

I am testing on the same machine, I am not sure if localhost/text.txt goes through NICs. Does it?

comment Who executed that particular command on my centos VPS
@cjc Well for some reasons mysqldump will hang and lock all tables, and then eventually it brings my site down. I am in talks with them to sort this out.

@cjc Thanks! I found the IP and it takes me to my backup company. I will ask them to stop playing with my server :)

Its my own user account with that uid. Though I previously checked cron logs for any particular culprit and didn't find any but I will recheck.

Please see update above. Basically 500 uid is my own useraccount (but I did not even touch the keyboard at that time). Since I restarted mysql to bring my site back, I can't run other commands...
