The fact that it runs fine initially then performance begins to degrade after a number of hours, I would start looking io statistics when the disk cache is full. aufs or diskd provide better performance so I would suggest using one of these methods for your cache_dir and see if you get an increase in performance. > > #access_log /var/log/squid/access.log squid > access_log none > > cache_log /var/log/squid/cache.log > > > > # Leave coredumps in the first cache dir > coredump_dir /var/spool/squid > > # Add any of your own refresh_pattern entries above these. > refresh_pattern ^ftp: 1440 20% 10080 > refresh_pattern ^gopher: 1440 0% 1440 > refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 > refresh_pattern . 0 20% 4320 > > >
