I have a Squid process running on RedHat 3 ES (Taroon). The machine has 2 GB memory. At the moment, the Squid process is 418 MB large, but 200 MB of this is in swap. Is this normal? I have irregularly dips on the proxy, when the request rate and throughput halves (from 200 req/s to slightly over 100, and from 1.2MB throughput to 0.7), and at the moment, the only thing that seems strange is the usage of swap. The swap space is really used by Squid: When I stop the proxy, swap space is cleared. Joost
