Regards, Kristian it seems like a good idea. if you will bind every squid instance to other ip address or you cand bind each one of them to a loopback interface with a mask of 32 bit i think you can manage theoretically to make it work. i never tried it and if it can work then i think i will do some use of this. but my question is: how do i bind an instance to a specific cpu\core?

Dear, i`m not expert for this issue but i think we cant specific the core for squid. it will run automaticly. 1 squid only can take 1 core. if i run 2 squid it will take 2 core ( using command top to view ). i tried SIBLING (htcp) and it worked , but i just want to know will it cause any trouble like unlimited loopback or memory leak or something like that. i hope any1 can explain it better for me.

Regards, Kristian What do you mean by unlimited loopback? if it works then i think loopback is your last problem. as far as i understand memory leaks will stay the same with one instance and two. i understand you compiled them yourself to make the instances with different settings? directories? etc.. Thanks Eliezer

Such configuration is one of the standard ways of getting SMP support out of Squid older than 3.2. http://wiki.squid-cache.org/MultipleInstances outlines the config options that need special attention. NP: the example socket balancing script usee TPROXY to manage the socket layer things. NAPT can also be used with older Squid which do not support TPROXYv4 Alternatively there is the CARP approach with a gateway parent and two caching siblings doing the heavy lifting: http://wiki.squid-cache.org/ConfigExamples/MultiCpuSystem Regards, Kristian it seems like a good idea. if you will bind every squid instance to other ip address or you cand bind each one of them to a loopback interface with a mask of 32 bit i think you can manage theoretically to make it work. i never tried it and if it can work then i think i will do some use of this. but my question is: how do i bind an instance to a specific cpu\core? Squid 3.1 and older rely completely on OS settings to bind a PID to a core. This is not a requirement for SMP support though, just a fancy bit of sugar. Amos -- Please be using Current Stable Squid 2.7.STABLE9 or 3.1.11 Beta testers wanted for 3.2.0.5
