At the low end, performance differences between a "Linux box configured as a cheap router" and a several $K Cisco/Juniper/Whatever router doing the same job are practically non-existent.
But the Linux box will likely require a little more baby-sitting, a little less "plug n play" that a comparable router "solution". The cost of that babysitting, unfortunately, does need to be factored in. At the high end, there's generally no comparison--for high-end routing, you *need* hardware-based routing to keep up with the "fat pipes". Funny story. In the lab at work, we have a Cisco switch, and a several $15.00 switches from a "off shore" manufacturer. The $15.00 switches slightly edge out the $800.00 Cisco in switching latency and jitter. Not by a huge margin, mind you, but it is rather funny that a consumer-grade $15.00 8-port 10/100 switch competes very favourably with a much more expensive one from a "big name". -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
