Last days I was busy by building and testing GCL and Maxima on
i86 Linux.
And I've got some strange results concerning gmp vs mp
performance.
It was stated that gmp should be faster than mp but my
observations give
exactly opposite result. Some figures:
Maxima 5.6 last CVS version + GCL 2.3.8beta3 (mp):
expand((x+y+z)^300)$ 99.8 sec
ratsimp((x+y+z)^300)$ 11.8 sec
Maxima 5.6 last CVS version + GCL 2.4.0 (gmp):
expand((x+y+z)^300)$ 239.2 sec
ratsimp((x+y+z)^300)$ 18.7 sec
In all other tests gmp is always slower although
the difference ranges from few percent up to two times.
Any ideas?
