Are there recommended system requirements for optimal performance?

The critical parameter for our product is system memory. We recommend 1 Gig of RAM for MetaVis (which is what we reserve by default). If you are running a lot of diagrams and or migrations simultaneously, we would recommend bumping that to 1.5 or 2 Gig (requires a parameter change). The O/S and processor is not as critical, but we would recommend a Dual Core if possible.
