Things to look into 1. Make sure you internally use persistent connections between Squid and the web servers. This cuts down on the number of initiated connections/s considerably. 2. Configure the unassigned port range as big as possible in your OS. On Linux this is set in /proc/sys/net/ipv4/ip_local_port_range. The biggest possible range is 1024-65535 and can sustain up to at least 500 connections/s continuous load squid->webservers. Regards Henrik
