No, it doesn't. The output of the run is four huge cProfile listings,
one for each plotting command tested. I manually searched the data for
long cumtime's that differed between the plots and typed the table myself.

I have also confirmed the speed differences on matplotlib 0.99.0 under
Ubuntu 9.10:

plot      0.629 CPU seconds
semilogx  3.430 CPU seconds
semilogy  1.044 CPU seconds
loglog    1.479 CPU seconds

I'll try to figure out why semilogx uses so much more mathtext than
semilogy, but if anyone familiar with the code is curious enough to
look into it they will probably beat me to the answer.
