Re: High response time at high concurrent connections

It soulds like ab is succeeding in generating a load high enough to impact performance already. You need to figure out where the bottlenecks are.

My message is intended as a helpful hint that you should not trust the stats from ab. You need to be measuring perf on the nginx and backend servers. Start by looking at the elapsed time in nginx and the response times of the backends.
