The benchmarks mentioned in the other responses are a good place to start. However, these single port numbers don't tell the whole story with multi-core where you may have eight cores on a node all talking to other nodes at the same time.
Multi-core requires thinking differently about performance. Talking about single application performance in a multi-core environment is like believing that all you need is a good quarterback to have a winning football team (apologies to all the non-US football fans) -- Doug > Hi, > > since the rush of emails seems to be over right now, I would like to > start another thread.
