I forgot to say that I tried it already. Even if it gave me no

I have it in 16 at this time together with a higher

Sincerley, any of the configuration changes I did gave me absolutely
nothing in relationship to the disk read access performance. That is
disappointing.

Should I go back and try ufs1 perhaps? Or is it that squid does not
work
well on 6.2?

Is it the same version of squid, same configuration, etc?

Yes, if you used to squid I am running the last 2.5-Stable14 version
which
run best on 4.11

OK, please provide further details of your system configuration
(dmesg, kernel config).



I have two server, the main server is a Supermicro Dualcore Dual Opteron
and the backup is a Athlon64 X2, both with 4GB

The disks are the same, only the onboard SCSI is Adaptec and the other is
LSI. Funny is that I have no difference regarding the disk read
performance wether I use the Opteron machine or the other

dmesg Opteron

dmesg X2

kernel config

thank you
Michel
