Here at Berkeley, lots if people use Ptolemy under XP.  I run Ptolemy regularly
under Windows 2003 Server R2.

The most likely cause of slowness would be running out of memory.  Memory is
set by invoking Kepler with the -Xmx option.  I believe Kepler is being
invoked with -Xmx512M, which means a maximum of 512 megabytes are allocated.
Increasing this to -Xmx1500M might help.  Under 32bit Windows, there is a
maximum of between 1600M and 1700M.

One thing to check for is how much memory is being used by doing
Tools -> Check System Settings

Another thing is to use a profiling tool, see

Someday, I'll take a look at
