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.

From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Leigh Sharpe Sent: Thursday, November 01, 2007 12:00 AM To: [email protected] Subject: [Bridge] Lowering CPU utilisation 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, Leigh
