[squid-users] Squid monitoring, access report shows upto 5 % to 7 % cache usage
Hi All For purpose of convincing about the squid cahce, I installed and started monitoring SQUID using mysar http://sourceforge.net/projects/mysar/; Is this % too low or average how much should a optimized squid setup give. Or should I dig into some more configuration to pump the cache % thanks Joseph John
