squid.conf runtime settings
Recommendations
- ipcache_size, fqdncache_size to 4096
- log_fqdn off (use Apache’s logresolve offline)
- Increase dns_children, redirect_children, authenticate_children based on usage statistics (see cachemgr.cgi front-end)
- Tweak refresh_pattern rules (Danger Will Robinson! -- I suggest starting with examples found in the squid mailing list archives)
