[squid-users] Slow Internet Access

Hi,
I'm using Squid Cache: Version 2.4.STABLE3 on a Redhat 7.2. It is working
transparently. Although most of the system sources are free, I have a slow
acces to internet.
Half of my bandwith is not being used. Can you suggest anything to me.
Below is an output from CacheManager-General Runtime Info.
