I'd expect one core at least to be maxed out. The hard disk isn't being hammered, RAM usage doesn't increase, so my question is: where is the bottle neck? I'm new to Mathematica so is this normal behaviour?

I can get it to do dead simple things, but anything vaguely complex it seems to choke on. Just getting it to replicate what I can do by hand seems an uphill struggle. Do many use it professionally or is it mainly used in education? > > Regards, > > Ben > > -- Ben, could you send an example. That would make it easier to talk about the issue you are seeing. Oliver
