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.
