Topic: nginx 0.5.35 with 2/4/8 mongrels - slow slow slow
Our sysadmin has been benchmarking this new Rails application, we've tried different setups, from 2 to 8 mongrels behind nginx, the mongrels don't seem to spread the load very well.
Regardless of how many mongrels we set up, a single one seems to be hit with 90M of memory usage and taking the CPU all the way to 80%-90%. All other mongrels, be it 1 or 7 are idling with 0 CPU usage and 20-21M of memory. Huh?
