Marcus, Thanks for the explanation. In my setup I chose to completely ignore this Ghz thing which may turn up to be a mistake. I am using the same number for Mhz as for the # of CPU cores, e.g. CPU (in MHz) 1 MHz
I was just concerned with the CPU weight thingy, but this should work just as well. -- Sent from the Delta quadrant using Borg technology!
