I'm using e1000 cards.
According to oprofile, around 50% of the time is spent in the e1000
driver.
Given that my load average is still under 0.5, I suspect I've got plenty
of room for the driver to handle more traffic before I need to worry too
much.

kind of NIC you are using? I
suggest you to use cards with NAPI featured in driver. _

Sharpe Hi All,
I have a box
with 12 bridges on it, each of which has 2 ports. When the traffic
level on the box reaches around 15-20Mbps on each bridge, my CPU utilisation
gets to about 90-95%. I would like to avoid
working the CPU that hard. Is there anything which can be done to get the CPU
utlilisation down a bit? I have plans for an even bigger bridge, but these
results indicate that it may not scale quite that
well. Regards, |
