We've recently seen a number of user bug reports against e1000 that the
in-kernel irqbalance code is detrimental to network latency. The algorithm
keeps swapping irq's for NICs from cpu to cpu causing extremely high network
latency (>1000ms).
What kernel versions? Some IRQ balancer fixes went in shortly after 2.6.17.
user reports show 2.6.17.1 having the problem, I'm trying to get more details
information, and will ask if 2.6.18rc3 or so does better for them.
