Hi all,
I am trying to run Squid on SMP machine, but it seems that it doesn't
use more than one processor. Is there anything to do or i should change
proxy software ? Of course it is on RH 9, one that ships with it.
Squid is a single-threaded application.
We're running squid on a 4 cpu box and a 2 cpu box and it's running on all CPUs here - using aufs storage system which according to the squid man page uses posix threads for async i/o:
