I am interested in a simple, bare bones setup and ballpark estimates at this point. There are lots of things that can be added on top of that, of course, and some of those things can be optimized to benefit from SMP support, but I am looking for a baseline estimate and relevant performance data from other servers. Thank you, Alex.
