Subject: [squid-users] very slow browsing and page is not displaed properly

Hi,

Version information and some statistics collected by me are as below. At times, my users complain the browsing becomes deadly slow and we page like yahoo, after much delay is displayed scattered and pictures are not visible rather "X" sign is displayed and after few times refresh screen becomes better.
