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. -- Harry A.
