I've been pretty happy running IBM x-series hardware using RHEL4. Usually it's PPS rather than throughput that will kill it, so if you're doing 250Mbit of DNS/I-mix/HTTP, you'll probably have very different results. There are some rx-ring tweaks for the NICs that are needed, but on the most part it's all out of the box (No custom kernel patches, and such - Just some sysctl settings).
I have two x3650s (Quad core) doing around 6-700Mbit/sec (40k pps) at around 20% CPU right now. No Quagga BGP, but that's minimal in terms of CPU. I've not been able to get much beyond 1Gb/sec on this environment because my ASAs are not configured to support more than one Gig into that particular network.

Hi All, Sorry if this is a repeat topic. I've done a fair bit of trawling but can't find anything concrete to base decisions on. I'm hoping someone can offer some advice on suitable hardware and kernel tweaks for using Linux as a router running bgpd via Quagga. We do this at the moment and our box manages under the 100Mbps level very effectively. Over the next year however we expect to push about 250Mbps outbound traffic with very little inbound (50Mbps simultaneously) and I'm seeing differing suggestions of what to do in order to move up to the 1Gbps level. It seems even a dual core box with expensive NICs and some kernel tweaks will accomplish this but we can't afford to get the hardware purchases wrong. We'd be looking to buy one live and one standby box within the next month or so. They will only run Quagga primarily with 'tc' for shaping. We're in the UK if it makes any difference. Any help massively appreciated, ideally from those doing the same in production environments. Thanks, Chris
