Running ps ax shows that no userland programs have > any significant loadings. 290 ints/sec is fine. The absolute minimum is 228, since there are always two clocks, running at 128Hz and 100Hz. So you're really getting ~60 interrupts/sec from your hardware. Run systat -v to see the breakdown in real time (irq summary is on the right of the screen). -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
