Thanks for the additional feedback. In terms of performance, I guess I was thinking about shared DMA channels and IRQs. The specs would be that the box would need to be able to push 20Mbits through it running gated. I was hoping to use the Intel Drivers, I have had great success using individual fxp cards. While on the topic of routing, someone mentioned that fiddling with the HZ value in my kernel can increase router performance. Is there any truth to this? Thanks again for the feedback, it is much appriciated. ---Mike ------------------------------------------------------------------------ Mike Tancsa, tel 01.519.651.3400 Network Administrator, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
