A newbie question: Does nginx use keepalives to upstream servers when using proxy? It does not appear to. I found the module for memcache and keepalives, which increased that performance allot. ---

Is it some synthetic microbenchmark results or real life server throughput increase? Microbenchmarks will expectedly show you latency decrease (theoretical maximum - ~ 3x, from 9 ip packets to 3), but I expect real life throughput results to be much smaller. Maxim D. ---
