16961	Unit tests 10 times slower on Linux if MySQL is used	aigarius@…	nobody	"Unit tests call the command 'ALTER TABLE tbl_name AUTO_INCREMENT=1' for all tables between test sets ( in db/backends/mysql/base.py:sql_flush ), in MySQL this command can take up to a second even for an empty table due to very old wishlist bug in MySQL. http://bugs.mysql.com/bug.php?id=37927

This bug causes a set of unittests to take 30 minutes to run (instead of 3 minutes, if the ALTER TABLE statements are removed)."	Cleanup/optimization	closed	Database layer (models, ORM)	1.3	Normal	fixed	mysql		Ready for checkin	1	0	0	0	0	0
