The slow down experienced when running Mathematica for
Windows under Windows 95 (or Windows NT) compared to 
Windows 3.x appears to be due to a conflict between
the mechanism built in to Mathematica for polling 
between the kernel and front end to share processor time
and that provided by the operating systems in Windows 95
and Windows NT.

Wolfram Research is currently testing a version of
Mathematica that resolves this conflict. This should
be available early in the New Year.

I you have been experiencing this slowdown contact Wolfram 
Research Technical Support directly (support at wri.com) for 
details on recieving this update when it is available.

I hope this helps.
