I once worked with a 4D/120 with 8 meg.  It was next to useless.  I don't 
think they should sell them like that (with that little memory).

You have twice as much memory but you also have twice as many processors.
Run gr_osview to see if it is spending all its time swapping.

The compilers are from MIPS and are generally considered excelent.
If you really are getting different answeres with optimised versus 
non-optimised code, you should report it to the hotline as a bug.  
(Narrow it down and post it to the net?)
