How to speed up MathCAD

How to speed up MathCAD

How to speed up MathCAD

My MathCAD seems really slow.  R13 on a duo-core Pentium at 2Ghz, 2GB Ram, 200Gb hard drive.  I don't have any solve blocks, matrix calculations or graphs.  I only reference two external text files.  No recursive calculations and very little Boolean logic.  A few simple If statements, otherwise just * + - / square root and square.  It just seems to take too long.  I always save as R12.mcd because the load and save was too slow otherwise.  What can be done to speed up calculations?

RE: How to speed up MathCAD

My Help/About says Mathcad, version 13.1 (604040953).  Is that the latest version?

RE: How to speed up MathCAD

Sounds about right.  

I'm running a 1 GHz P4, but it's only a bit slow.  You might try disabling hardware acceleration on the graphics and mouse.

Try loosening your Constraint Tolerance and Convergence Tolerance.  I've found these to have a significant impact on calculation time when taking integrals.

Many would say that the latest version is 11.2a; all "newer" are still in beta. winky smile
