    Proxy Server - slow internet


    I have squid proxy server running on CentOS 5.5

    This past few days, I found out that our internet become very slow when the squid server is connected to the network. Upon checking our bandwidth utilization, it max out the upstream of our internet. Nobody from our network is uploading data. This could be the server?

    Here's my squid.conf
    auth_param basic children 5
    auth_param basic realm Squid proxy-caching web server
    auth_param basic credentialsttl 2 hours
    auth_param basic casesensitive off
    acl blocksites url_regex "/etc/squid/block.sites.acl"

    coredump_dir /var/spool/squid
    I've setup my IPTABLES for transparent proxy and working.

    I know the upload thing is the issue, but I could not find out where to check.

    Hope you can help.
