Comment (by ncohen):
> Interestingly, arithmetic with infinity also shows up quite high in the
profiling reports (up to 10% of the time), so optimizing
`src/sage/rings/infinity.py` will also give some speedup.
Aahahah. Yaeh, Vincent has been fighting a lot with some abstractions we
have, which makes code run *much* slower. For `+oo` he advises to solve
the problem by using float("inf") instead of Infinity. It is *MUCH*
faster.
At some point he got some crazy somewhere by adding 'from math import
sqrt' in a module to overwrite Sage's sqrt function.
