Hmm. That is a good point. If there is little difference, then I suppose I'll blame buildout.
$ bin/django print_time 2014-03-05T22:07:33.051634 before test 2014-03-05T22:07:40.202247 command has been run That is A difference of 7 seconds, significantly better. $ strace bin/django print_time 2> cmdtrace cat cmdtrace | wc -l 54361 $ cat cmdtrace | grep 'open(' | wc -l 34233 $ cat cmdtrace | grep 'stat64(' | wc -l 13625 $ cat cmdtrace | grep 'read(' | wc -l 2706 $ cat cmdtrace | grep 'fstat64(' | wc -l 2377 $ cat cmdtrace | grep 'close(' | wc -l 1563 $ cat cmdtrace | grep 'ENOENT (No such file or directory)' | wc -l 41561 There are still almost as many files being sought for and not opened however. I suppose that means that failing to find a file on disc is actually not that costly. The difference between running a command and running a test also suggests that either: 1) Linode disc performance varies throughout the day and is better outside buisiness hours? Nope. 2014-03-05T22:20:33.604757 before test nosetests --verbosity 1 match_mentors -anow -s To reuse old database "test_02_06_18_29" for speed, set env var REUSE_DB=1.

I should have broken it out and ran that test. I'll do that now. 2014-03-05T22:23:05.650883 before test nosetests --verbosity 1 match_mentors -anow -s To reuse old database "test_02_06_18_29" for speed, set env var REUSE_DB=1. Creating test database for alias 'default'... 2014-03-05T22:23:42.127545 test has begun That is still 37 seconds, so it is almost certainly something in the test discovery process. I suppose this means that digging up and mapping out the piping that runs through nose <https://github.com/nose-devs/nose>, django-nose<https://github.com/django-nose/django-nose>, the django test-discovery code, and unittest.py is in order. I suppose that will build character. -- *Andrew Farrell* Software Engineer *|* MassChallenge, Inc. 1.888.782.7820x720 *|* amfarr...@masschallenge.org ONE Marina Park Drive *|* Boston, MA 02210 * Free m entorship, resources, coworking space.
