[squid-users] WCCP+ Squid Slowing internet browsing , how to improve it ?

Hi,

Squid-2.5-STABLE12 + ip_gre WCCP + RHEL v4 U2 + 4Gigs RAM + Cache
Dir to be 45 Gigs, but only 20Gigs now

I have a high volume network ( /19)
I had to increase the number of file descriptors and rebuild squid.
Now it works Ok,

But I notice a major slowness in browsing the internet. Plus site
with streaming media take too much time to load. From some parts of my
network, I get "Unable to reach Website answer"

This is my config,
---------------------------
iptables -nL -t nat
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
DNAT tcp -- [MyNet]/19 ![MyNet]/19 tcp dpt:80 to:[Cache IP]:3128
