Hi, Maybe: Khan, Sohel; Waheed, Abdul (2003): High Performance Routing on PCshttp://www.ccse.kfupm.edu.sa/~sohel/networking/references/Routing.pdf A rule of thumb: - with current COTS hardware and (standard) PCI Bus, you can reach the maximum of the PCI bus bandwidth. That's 1 GB/s, e.h. two NICs with 500 Meg/s each ( one in and one out ) - with PCI-X and in the future PCI-express you'll for sure be able to reach more performance. I didnt find a sponsor for a test-lab yet :) - in DoS secnarios it may get worse :/ I heavily depends on driver type (polling and NAPI preferred). The problem with the performace is _always_ the number of interrupts, nothing else is a bottleneck (well, we didn't talk about thousands of iptables rules yet, but you ask for a 'maximum'). - The question you have to ask in high-performance scenarios is not "MBit/s" but MPPS (megapackets per seconds). FreeBSD and Linux broke the 1 MPPS barrier some time ago (on dual xeons). rgds, Andreas Fermín Galán Márquez wrote: > Hi, > > I wonder about the performance of a Linux box used as router (I guest I'm > not the first :).
