hey gurus -- i have a HP server with 4*dual core AMD opteron processors running 2.6.9-42 SMP kernel -- one of my DBAs complained of poor performance while running an SQL query -- now when I check the 'mpstat -P ALL 5 ' o/p - I see that CPU 0 is completely busy (idle 0%) most of the time -- while the other CPUs are close to 99% idle -- I did a cat /proc/interrupts I see that CPU0 is indeed having high values corresponding to ethernet devices , other PCI devices , RAID controller and the timer as well --- I also checked that we are running irqbalance daemon and please note that we are running the kernel with noapic option -- not sure if that matters at all
any inputs you may render are higlhly appreciated Thanks!! _______________________________________________ To unsubscribe, email [EMAIL PROTECTED] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
