New issue 2585 by [email protected]: Tests take too much memory
http://code.google.com/p/sympy/issues/detail?id=2585
It seems that our tests take too much memory. I run the tests and kept an
eye on memory usage (on my machine), and: by the time we get to polys, it's
already at more than 200MB, ~330 after series, then hyperexpand and ode add
another 50 and 40, for a total of ~450 MB... (doctests run up to ~100MB).
I've tested with py.test (git checkout rlamy/pybench) too but it's about
the same. Obviously this isn't good, but it also causes our Jenkins server
to swap which kills the execution time.
Apparently, the tests aren't cleaning up after themselves and so the memory
keeps growing. On IRC, bdesk pointed out this issue on MoinMoin [1]:
py.test run leaks memory. I'll try to investigate some more, see if it's
something that could be fixed upstream in py.test (thus providing a nice
incentive to switch) or maybe it can be done on our end.
