Marcos, Ubuntu should work fine with an SMP kernel for squid. Just to double check, with your setup have you followed these guidelines? http://wiki.squid-cache.org/MultipleInstances one of the most important things to check is that you have different PID's for every instance of squid, see "pid_filename" Also, how many cpu's does that box have? Do you see squid always using the same one (I.E. CPU2) Saul W -----Original Message----- From: Marcos Camões Bourgeaiseau [mailto:marcoscamoes@xxxxxxxxxxxxx] Sent: Tuesday, March 11, 2008 4:34 PM To: saul waizer; squid-users@xxxxxxxxxxxxxxx Subject: Re: Multi processors Sorry about that. It is a Ubuntu Feisty with a re-compiled Kernel version 2.6.15.7. We just took out some harware modules. We tried some newer Kernel but we couldn't make it work with the hadware that we have here. And just for clarity: It was OK to put four or more instances running at the same time, but all of those instances keep using the same processor and only that ONE processor. It is such a waste. And we have very limited material to work here.
