Ample amounts of filedescriptors. Give Squid 32K filedescriptors or so (--max-fd configure option, or max_filedescriptors config option in squid.conf 2.7) maxed number of outgoing TCP ports. (ip_local_port_range sysctl) persistent connections enabled (default) aufs cache_dir type, with two cache_dir per drive. L1=128, L2=256. Make sure to leave some GB of ram for OS + fs cache. Don't be too agressive about the Squid memory usage. Do not configure a swap. Instead leave sufficient margin in the memory usage.. Should also give some advice on which filesystem to use, but ext3 is probably fine. reiserfs is also a good candidate but may need the notail mount option. noatime mount option on the cache drives.
