I have the following question. My system is 2x 2.4Ghz Xeons. Linux kernel 2.4.18 compiled with SMP support sees it as four processors. SMP-disabled kernel sees one, of course. I would like to know, how will it influence the system performance, if I run a UP kernel? What does the kernel SMP support add? Just some API for additinal multiprocessor control? Will the SMP-enabled kernel run faster than the UP one? That's what I would like to know. Thanks!
