Re: [squid-users] Use squid as tiny proxy

This is what i have done to tune the non-caching squid box. Did i miss out
anything?

        /etc/sysctl.conf

        net.ipv4.tcp_keepalive_probes = 8
        net.ipv4.tcp_syn_retries = 2
        net.ipv4.tcp_synack_retries = 2
        net.ipv4.tcp_keepalive_time = 600
        net.ipv4.tcp_wmem = 8192 16384 131072
        net.ipv4.tcp_rmem = 65536 65536 174760
        net.ipv4.tcp_fin_timeout = 4

When the load is about 100 req/s, i got the following stats, is this
consider normal?

        fd 1200
        total connection 14000
        est connection 4000

Really dream of hitting 700req/s... :)
