New issue 424: Running on multiple CPUs significantly slower https://bitbucket.org/hpk42/pytest/issue/424/running-on-multiple-cpus-significantly
Trevor Bekolay: Before today, with `pytest-xdist`, `py.test -n X` would result in significant speedups. Today, it's significantly slower. ``` $ py.test ================================== test session starts =========================== platform linux2 -- Python 2.7.6 -- pytest-2.5.1 plugins: xdist collected 81 items ................................................................................. =============================== 81 passed in 32.63 seconds ======================= $ py.test -n 2 ================================== test session starts ============================ platform linux2 -- Python 2.7.6 -- pytest-2.5.1 plugins: xdist gw0 [81] / gw1 [81] scheduling tests via LoadScheduling ................................................................................. ============================== 81 passed in 252.04 seconds ======================= ``` The only thing that's changed since yesterday is that I did an apt update that installed a new version of Python 2.7. I'm on Debian unstable (sid). All of the Python2.7 packages were updated from version 2.7.6-4 to 2.7.6-5. Is it possible that one of those updates broke thing? I recreated my virtualenvs, but I'm still experiencing slowdown. _______________________________________________ pytest-commit mailing list pytest-commit@python.org https://mail.python.org/mailman/listinfo/pytest-commit
