I've edited my answer at
https://ask.sagemath.org/question/45959/grad-at-glacial-speed/
to indicate how to change the simplification algorithm.
Best wishes,

i had sage perform grad() on a scalar field and the calculation was really
slow. grad() consists of several steps and apparently the derivative() is
not the issue, but rather the simplification of the resulting terms
thereafter. The process is described here:

Can the following problem be solved by Sage:
Prove that there is a matrix with 117 elements containing the digits such
that one can read the squares of the numbers 1, 2, ..., 100.
Here read means that you fix the starting position and direction (8
possibilities) and then go in that direction, c
Hey thanks,
I took your advice, and everything is working fine now. Didn't have to use
sudo for the rest of the process. Clearly i'm new to linux and didn't know
that you could change file ownership like that. I was also able to get my
new package installed.
