Fernando, Doing a quick google search I see other people have also reported problems with the on board Broadcom BCM5708 on the dells. Can you try another network card like the Intel Pro/1000 MT (OpenBSD interface name: em0) ?
My place of business transfers an average of 450Mbit with OpenBSD 4.1/4.2 with ALTQ (HFSC) without issue. CPU usage for the interrupts are around 33% on a amd64 2.2GHz. -- Calomel @ http://calomel.org Open Source Research and Reference On Mon, Nov 12, 2007 at 02:05:54PM -0300, Fernando Braga wrote: >Hi, > >I've setup a bridge over a 200Mb link, and everytime I turn ALTQ on, >top shows interrupts at 99.2%.
