Hello, I am runnign freebsd 5.2.1 on 386 arch with two rl lan cards. My mainboard is on VIA KT 266A with AMD athlon 1.1. I read man polling and i have HZ=1000. My problem is that when i set up sysctl variable kern.polling.enable=1 my interrupts greatly increase. When my system is idle and indicate 0-1% interrupts with out polling. and when i turn on polling interrupts goes up to about 20% on idle system. Is it normal ? I never before use polling and i dont know that i have something bad in my system ? Can somebody explain me this ? thx -- Best Regards: GiZmen UNIX is user-friendly; it's just picky about its friends UNIX is simple; it just takes a genius to understand its simplicity
