can someone give me hints on what hardware would be best suited to run big fat tor exit nodes connected with multiple 1gbps or 10gps links? We are considering putting some fat boxes near major internet exchanges of the world.
Modern Xeon, AES-NI is helpful, HT is not very helpful (but not hurtful either), higher clock rate is more helpful than more cores. 4GB of RAM per core, you can probably get away with 2GB/core but why skimp. Noisetor uses most of a 4-core X3350 2.6 GHz to push ~500 Mbps symmetric. That's without AES-NI, so I'd expect a quadcore 2.5 GHz AES-NI to be able to fill a 1Gbps pipe.
AMD doesn't seem to make any server CPUs that are useful for this application, unfortunately.
