I ran a test with Axiom and it takes about 45 seconds on
a slower, single processor box.

Are you the author of the code for Maple, MMA, or Pari?
If this is a simple test and you are aware of ways to
improve the performance, did you post improved code?

It is trivial to complain that there COULD be better code.
It is somewhat more of a challenge to write that code.
So write the improved code and benchmark your version.
I would be curious to see how much better you can do.

There is no such thing as a simple job.
