just a thing.As I understand the users go to squid and squid goes to the
web page?Something like this

[network]-----8080----[eth0 linux eth1]----80---web.
So if you limit the port 80 traffic on eth1 it should slow down squid
but you dont want to limit traffic on eth0's 8080 because what's the use
of a proxy then?
This is just how I see it?
