The calculus.py module likely doesn't use ATLAS at all. The only thing
that would have much of an impact on speed would be Maxima, probably.
What hardware are you using exactly? On a 2.6Ghz machine I get:
teragon:calculus was$ sage -t calculus.py
sage -t calculus.py
[44.3 s]
What happens if you do
sage -t --verbose calculus.py
i.e., do you visibly see any doctests taking a really long time? For
me the main
time takers are some plots (this should be optimized soon, actually.)
I seem to vaguely recall maybe you are using a different version of Maxima
than the one in Sage? Maybe the newer Maxima is simply faster at some
key operations, or maybe we compile clisp or maxima in some stupid
way that makes it slower (that would be _very_ interesting to get to the
bottom of, it is the case).
