Hello,
I can't seem to find an option to disable multiqueue in the igb driver
which comes with the 2.6.28.x kernel. The module parameter IntMode is
not supported.
With 6 nics operational i now use 54 interrupts. My hardware (Dell
PE1950 / Intel 5000X chipset), spreads all interrupts accross all 8 CPU
cores. This looks really ugly (attached).
Thanks for any advice,
Patrick Schreurs
