Hi, In that case I recommend you to take a look at the debugfs patch already in there, based on that it should be pretty straightforward to do it what you want: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f51de243 It already prints out queue-napi.weight

Hi, I would check whether GRO is enabled under Dom0 or not (ethtool -k ethX). Comparing top during test (especially that which context use how many percentage), and the number of interrupts per second (grep eth /proc/interrupts) would be interesting too. Regards, Zoltan On 28/11/14 02:29,
