[squid-users] More Incomming Traffic than Outgoing Squid 2.4

Hello,

We are running squid 2.4STABLE1 on a Linux 2.4.3 box.
We see that the incoming traffic is higher than the outgoing
  ( 10Mbit outgoing for 20Mbit incoming)

   +--------+ +-------+
   | Tunnel |-----requests----->| SQUID |
   | NAT |<----pages---------| |
   +--------+ +-------+
        ^ ^

        +-------- INTERNET---------+

The Squid server has 1 network interface where all the
   requests and traffic is comming in and out.

We tried to set quick_abort_min to -1 with no effect.
And then range_offset_limit to 0 with no effect

The byte-hit-ratio is mostly negative and varies from +27% to -400%
The hit-ratio is about 9.9% with maximum 44%
Objects in cahe 500,000
Average service time 12000
CPU load is about 50% (max 82%)

Some more info:
fdsetsize is 8192
SOMAXCONN is 16386
Using 3 reiserfs disks of 14Gbytes and DISKD
RAM 1Gbyte, CPU PIII 866Mhz
