Squid: too slow for some websites

    Dear members,

    We have two squid servers (2.5.STABLE12), first on RHEL 4 and other on FreeBSD 6.1. Users are connected to Squid Servers, and Squid Servers are connected to Gateway.

    My problem is that our own website.. say mysite.com is opening very slow, every user is complaining.
    If we bypass squid, then its very fine. We also needs to block caching of our website. No page/images should be cached of our website at all because its a dynamic site and we need to view latest contents quickly after uploads.

    Both squid have identical squid.conf (apart from directory paths) and the strange thing is we are unable to open some websites(or extremely slow) like howtoforge.com, mysite.com using when connecting with RHEL but things improves with FreeBSD. There's are 100 users connected with RHEL and around 75 with FreeBSD. Some users are using Linux while others are on Windows but facing the same problem.

    Here is my squid.conf (from bsd squid), I request you to please have a look and advice:

    Any errors in your logs? did you disable SELinux on RedHat?
