Hello, Usually my proxy (Squid 2.5 STABLE10 on RH Linux) performs quite well, but occasionally I see a drop in the number of successful requests (it's usually around 200/s, but drops to as low as 100/s). I've written a small performance test which uses curl to measure time_total, time_connect and speed_download. The script runs on the same machine. Most of the time, the connect time is close to 0 ms, but occasionally I see a spike, largest I've seen is around 6 seconds(!) connect time. time_total - time_connect is reasonably constant (somewhere between 600 and 800 ms) Does anyone have an idea where I could start to find a cause of this strange behaviour? Kernel settings? TCP settings? Squid settings? Joost
