I have just upgraded from the standard version of Mma 2.2 (no
coprocessor support) to the "enhanced" version for $145. Wolfram told me
that the standard version was no longer supported. Well I just installed
the enhanced version expecting improvement in performance. Well guess
what? The enhanced version is *slower* than the standard version! No
kidding! The test I use for timing is the following code:
Plot3D[Sin[x]*Cos[y],{x,-Pi,Pi},{y,-Pi,Pi}]
The timing is as follows:
Standard:
Pentium 75 - 2.8 s
Pentium 120 - 1.9 s
"Enhanced":
Pentium 120 - 2.8-3.5 s (highly variable)
All timings were run under Win 95 with 16 MB memory with screen
conditions set to be the same and graphing options se the same.
What gives here - why is my co-processor version slower? I installed the
Win-95 patch and the system runs well except for the following: (a) I
cannot interrupt the calculations, (a) Timing doesn't work when I do
loops anymore - I need this feature to publish my research.
Did I do something wrong? Can I fix this? Will The version of Mma for
Win 95 be faster? I am very frustrated - please help if you can.
