Hi all, So i'm doing a lot more ab testing. I isolated out the performance on paster and basically wrote an action that does nothing. I find the following:
Running ab WITHOUT concurrency (with 4 paster processes OR with only 1 paster). I get a LOWER requests per second and higher average response time VS Running ab WITH concurrency set to 200 (with 4 paster processes OR 1 paster process) I don't understandt his completely. Why would single requests, one after the other be slower than concurrency? Note that lighttpd is doing the load balancing in the case of 4 paster processes. Is it because of starting new connections, am I not configuing something correctly to take care of caching known connections that are getting reestablished? When I add a single db hit (primary key lookup to mysql), my performance goes way down, but still consistently across both types of tests.
