[Python-Dev] [ python-Bugs-1124637 ] test_subprocess is far too slow (fwd)

[Peter Astrand]

I'd like to have your opinion on this bug. Personally, I'd prefer to keep
test_no_leaking as it is, but if you think otherwise...

One thing that actually can motivate that test_subprocess takes 20% of the
overall time is that this test is a good generic Python stress test - this
test might catch some other startup race condition, for example.

Regards,
Åstrand

Summary: test_subprocess is far too slow

Initial Comment:
test_subprocess takes multiple minutes.  I'm pretty
sure it's "test_no_leaking".  It should either be sped
up or only tested when some -u argument is passed to
regrtest.

Bog standard linux pc -- p3 933, 384 megs of ram.

"$ time ./python ../Lib/test/regrtest.py test_subprocess"
reports 2 minutes 7.  This is a debug build, a release build
might be quicker.  A run of the entire test suite takes a
hair over nine minutes, so 20-odd % of the time seems to be
test_subprocess.

It also takes ages on my old-ish ibook (600 Mhz G3, also 384
megs of ram), but that's at home and I can't time it.

Tell me a bit about your type of OS and hardware. On my
machine (P4 2.66 GHz with Linux), the test takes 28 seconds.
