This was on 64 bit GNU/Linux (Fedora release 12) running on a dual
processor machine with two Intel Core 2 CPUs (each 2.4GHz, 4Gb
cache). I have included the contents of /proc/cpuinfo at the bottom
of this reply.

I am comparing Sage 4.3.5 (which I am pretty sure was built from
source) with MAGMA V2.16-7. The Sage script I ran was:
---start of Sage code---
R.<x,y,z> = PolynomialRing(ZZ,3)
f = x*y^3*z^2 + x^2*y^2*z + x*y^3*z + x*y^2*z^2 + y^3*z^2 + y^3*z +
2*y^2*z^2 + 2*x*y*z + y^2*z + y*z^2 + y^2 + 2*y*z + z
curr = 1
t=cputime()
for i in range(1,101):
curr = curr * f
print i, cputime(t)
print get_memory_usage()
---end of Sage code---
The Magma script I ran was:
---start of Magma code---
R<x,y,z> := PolynomialRing(Integers(),3);
f := x*y^3*z^2 + x^2*y^2*z + x*y^3*z + x*y^2*z^2 + y^3*z^2 + y^3*z +
2*y^2*z^2 + 2*x*y*z + y^2*z + y*z^2 + y^2 + 2*y*z + z;
curr := 1;
t:=Cputime();
for i in [1..100] do
curr := curr * f;
print i, Cputime(t);
end for;
---end of Magma code---
Please let me know if you need more information, or if I am doing
anything that is obviously stupid.
The results of running 'cat /proc/cpuinfo' follow.
Best,
Tom
