Re: [squid-users] Performance Tuning - Transparent Cache

I already did that!

(On FreeBSD 4.3)

/sbin/sysctl -w kern.ipc.somaxconn=1024
/sbin/sysctl -w net.inet.tcp.delayed_ack=0
/sbin/sysctl -w net.inet.ip.portrange.last=40000
/sbin/sysctl -w kern.maxfiles=16384
/sbin/sysctl -w net.inet.tcp.sendspace=32768
/sbin/sysctl -w net.inet.tcp.recvspace=32768
