Benchmarks should measure memory usage too, of course. Sadly that is
not possible in standard cPython.
It's actually very easy in standard CPython, using sys.getsizeof.
Yes, you can query each python object about how big it thinks it is.
What I'm speaking of is more like:
start_allocs, start_mem = allocator.get_current()
allocator.reset_limits()
run_complicated_tests()
end_allocs, end_mem = allocator.get=current()
This is easy in a debug build, using sys.getobjects(). In a release
build, you can use pympler:
start = pympler.muppy.get_size(pympler.muppy.get_objects())
run_complicated_tests()
end = pympler.muppy.get_size(pympler.muppy.get_objects())
print "delta mem: %d" % (end-start)
