We have one of these also, though I'm running RedHat AS 2.1. I'm seeing the same thing, and it was unnerving until I realised that I *should* be seeing 4 CPUs! If I understand it correctly, the new Pentiums have something called "hyper-threading", which makes each CPU act as if it were two, to get better utilization. The newer kernels are able to take advantage of this, and it increases your performance considerably. Or, at least, the simple tests I did with 'top' and such sure seemed to say so.
