Hi,
I'm trying to tune machine with 8.2-STABLE for heavy network load and
now playing with netisr. Could anyone explain me why actually works only
one netisr thread if I set them to 8?
Can you please supply `nestat -Q` output and clarify you usage pattern
? (I mean, this is router/web server/some kind of traffic receiver/etc..).
For example, flow policy does not balance traffic from single flow
between different CPUs.
loader.conf:
net.isr.maxthreads=8
net.isr.bindthreads=0 (also tried set to 1)
hw.em.rxd=4096
(net.isr.numthreads is 8 after reboot, `procstat -t 12' shows me 8
netisr threads)
sysctl.conf:
net.isr.direct=0
net.isr.direct_force=0 (also tried hybrid mode when direct=1, but
force_direct=0)
NIC:
em0@pci0:4:0:0: class=0x020000 card=0x109615d9 chip=0x10968086 rev=0x01
hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel PRO/1000 EB (Intel PRO/1000 EB)'
class = network
subclass = ethernet
No polling.
