#11449: Performance regression loading from fixtures in 1.1 & trunk
---------------------------+------------------------------------------------
 Reporter:  novalis        |       Owner:  nobody    
   Status:  new            |   Milestone:            
Component:  Uncategorized  |     Version:  1.1-beta-1
 Keywords:                 |       Stage:  Unreviewed
Has_patch:  0              |  
---------------------------+------------------------------------------------
 I have created a test that does nothing but read in a fixture.  It goes
 significantly slower on Django 1.1-beta and trunk than it does in Django
 1.0.

 1.0: Ran 1 test in 4.940s
 1.1: Ran 1 test in 21.541s
 trunk: Ran 1 test in 21.228s

 My rejected patch in #11181 reduces cuts each of these times in half --
 but does not fix the regression.

Comment:

 I have to say this conflicts with my personal experience - I have found
 that tests under v1.1 run much faster than v1.0 tests, as a result of the
 transactional test case changes.

 Would you care to share your exact test code?
