That's irrelevant. What matters is how long Maple, Mathematica,
Matlab, Maxima, Pari, and Magma take to start.
After repeatedly running the command on sage.math, this is how things stabilize:
Pari 0.030s
Python 0.046s
Maple 0.111s
Maxima 0.456s
Mathematica 0.524s
Matlab 0.844s
Magma 0.971s
Sage 1.658s
This is probably the only benchmark that involves a "function" that
*everybody* uses -- starting up the program. Sage is currently dead
last, and by a lot. Python and Pari are both by far the fastest to
startup, so at least it isn't Python's fault :-).
