Re[2]: [squid-users] outside squid link overload.

Hi Amos,

I meant "I do not restrict my customers' bandwidth anywhere".
I already added Henrik's suggestions to config. But still i get
traffic increase.
Right now I am running squid-3.0.STABLE10.

My topology is:

Clients-router-Internet
          |
        Squid

And i get increase on a router-internet link.
The statistics I've sent is captured on router-squid link. It shows
that Squid gets more from internet then gives:
>> From router to Squid:
>> 30 second input rate 1980000 bits/sec, 399 packets/sec
>> From Squid to router:
>> 30 second output rate 2164000 bits/sec, 381 packets/sec
I am definitely sure that Squid sucks more from Internet then gives to
customers.
At the moment I am trying to change a topology and to use
delay-pools... Hope it will save me :)
Thanks for replies!
