[This is an email copy of a Usenet post to "sci.math.symbolic"]

Here are some results on my 700 MHz PIII Linux machine using (not yet released 
but getting close) Maxima 5.9.0:

Maxima 5.9.0 (old, using GCL) : 112.21 seconds
Maxima 5.9.0 (new*, using GCL):  18.80 seconds
Maxima 5.9.0 (using clisp)    :  31.30 seconds
Maxima 5.9.0 (using CMUCL)    :   7.91 seconds

*The new version includes some default memory preallocation with GCL. The
preallocation hasn't made it into cvs yet.

Given that the numbers below come from a 933 MHz machine, I think the above
numbers compare pretty well.
