Hi,

I’m trying to use nginx as forward proxy with high loaded server on  
CentOS 5.4. My stats showing good results (about memory/cpu usage and  
traffic). But Apache benchmark showing some percentage of lagged  
sessions. If I’m using Apache as forward proxy I don’t see this lags.

Can you recommend me some config changes or may be I can boost nginx up  
other way?
