[Maxima] maxima is 100 times slower than maple

If I remember correctly, Maple is capable of doing a lot of "memoization" & "hash consing", so that redundant computations are recognized & not performed redundantly.
For some computations this might help a lot.

I don't think that either Maxima or Mathematica or Maple is especially fast or slow in general, I think they just do some things in different ways, and a factor of 100 is not much if different algorithms are used, or e.g. simplifications are run on every step or only in the end. A single use case doesn't really tell a lot on which algorithm is better.

>Hello, list. I am comparing the speed of execution of maple and maxima programs. And maple is 100 times faster then maxima for symbolic computation. For example, to run the attached program maxima needs about
>50 seconds on my laptop. To run the same program(of course, syntax of program must be accordingly changed) maple needs about 0.5 seconds.
>I am using debian stable, maxima is configured to use sbcl, version of maxima is 5.27.0 Is there any possibility to speed up maxima?
