It has come to my attention that even with FreeBSD 3.3-RELEASE SMP support, I do not see two processes marked runnable at any given time. My processors are both Intel (P3) and my motherboard is well supported (ASUS). It is my understanding that SMP support is not just to allow ping ponging of processes between multiple CPU's for tasking purposes, but to allow more than one concurrently running thread and or process on seperate CPU's. I have worked with many SMP-supporting OS's such as Linux (ugh), Solaris, Solaris X86 etc... All of which show more than one process marked as runnable at any given time, and yet I see only a single process marked runnable on this FreeBSD machine at any given point. Whats more, benchmarks and other information from MySQL show that threads are not executing concurrently accross the dual CPU architecture which I have. I'm quite sure I have the kernel options configured correctly, which is why Im so confused about this. So, without further ado, I ask a simple question, does FreeBSD 4.0-R fix this problem? Or is there some way I can fix it with 3.3-R such that the SMP is working properly and or most efficiently, and allowing threads to span CPU's and execute concurrently, and likewise with processes? Thank you for your time. -- Brent York york@mediarack.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
