[squid-users] Slow Internet with squid

Hello.

I am puzzled to see how my bandwidth is used when running squid. I have
a total of 25M/3M of bandwidth, lately I've noticed with iptraf that my
external interface traffic/bandwidth is almost maxed out at 24.8M and my
internal interface (squid) is only at 2.9M as a result most clients have
been calling saying "their internet is slow".

I'm wondering why that big of a difference on the interfaces' traffic.

This is what cachemgr shows:

Squid Object Cache: Version 3.1.14

Please help me understand why this is happening and if there is a solution to make squid perform better.

Thanks.
