Good morning, I've noticed 33K interrupts/sec on an em(4) gigabit interface on a box. This many interrupts seemed a bit too high, so I thought I should enable polling(4). After enabling it i've got 55K per second, even higher.
I've just done "ifconfig em1 polling", and by this the number of interrupts increased. options DEVICE_POLLING is in the kernel. The system is: FreeBSD lvs1.in.publishing.hu 6.2-RELEASE-p6 FreeBSD 6.2-RELEASE-p6 #2: Fri Jul 27 10:57:50 UTC 2007 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/LVS i386 Isn't polling supposed to lower the interrupt load? What am I doing wrong here? I don't think this is the expected behaviour, at least, not by me. Sincerely, Gergely Czuczy mailto: [EMAIL PROTECTED] -- Weenies test. Geniuses solve problems that arise.
