However is there any possibility of the following: > I don't know if there's a way to split the interrupt request for each bce's Rx and Tx, > which means a total of four IRQs, and eventually four cores (or 4 CPUs) > for the transactions. With this way, the IDLE processors would be utilized. What I mean here is, for the two interfaces: one IRQ for bce0 Rx one IRQ for bce0 Tx one IRQ for bce1 Rx one IRQ for bce1 Tx Thanks, Won ________________________________ From: Jeremy Chadwick To: Won De Erick Cc: freebsd-hardware@freebsd.org Sent: Thursday, November 13, 2008 3:46:02 PM Subject: Re: IRQ31 and IRQ32 on HPDL585 running FreeBSD 7.0 are consuming HIGH CPU usage On Wed, Nov 12, 2008 at 11:38:15PM -0800, Won De Erick wrote: > I am conducting a CPU utilization testing with my box(HP DL 585 running FreeBSD 7.0), and come up with the results below: > > 52 root 1 -68 - 0K 16K CPU11 b 123:53 100.00% irq32: bce1 > 51 root 1 -68 - 0K 16K CPU10 a 119:28 89.06% irq31: bce0 > > irq31 and irq32 are consuming high CPU usage, which i think the cause of hard reset. There was a ***major*** bce(4) cleanup that just happened. Your 7.0 box will not have these changes. Please upgrade your box to RELENG_7 (a.k.a. 7.1-PRERELEASE), csup'd recently (today preferably), and try your tests again: http://lists.freebsd.org/pipermail/freebsd-stable/2008-November/046482.html -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
