Like I said, remove both pipes and queues to test. However, pipes
_can_ be used without queues, but that is irrelevant here. Try
setting HZ to 1000 in your kernel config, recompile, reboot, and test
again. You should see something between a slight improvement to a
ten-fold improvement.
Already tried that and it did improve things a little. I tried setting the HZ to 1000 and it didn't make much of a difference. Is there a larger number that actually works well?
Thanks,
John
