Our experience is that MMA V2.2.3 definitely runs faster under Win3.11 
than it does under Win95.

We especially notice it when using MMA and Nodal2 (written by Macallan 
Consulting) for circuit analysis and attempting to Simplify[H()] where 
 H() is the circuit transfer function generated by NodalAnalyze. I 
haven't done any specific timings but under Win95 the process takes 
considerably longer.  Also, we've noticed that V3.0/Win95 runs much 
faster than V2.2.3 on Win 95.

Our platform is Pentium 100, 16MB RAM and under Win3.11 I had about a 
20MB swap file.
