How to control the total requests in Ngnix

[Peter Booth]

I’m a situation where you are confident that the workload is coming from a DDOS attack and not a real user.

For this example the limit is very low and nodelay wouldn’t seem appropriate. If you look at the techempower benchmark results you can see that a single vote VM should be able to serve over 10,000 requests per sec.
