15119	MySQL backend generates unnecessary commands	Luke Sneeringer	Aymeric Augustin	"When looking at our MySQL (InnoDB) instance that powers our Django application, our DBA reports that the com_admin_commands variable is extremely high: MySQL is running an administrative command (such as a ping) roughly three times for every query that goes off.

There's a roughly 2.5 year old discussion about this on django-users where the behavior is explained: http://www.mail-archive.com/django-users@googlegroups.com/msg55094.html
This is probably a pretty small amount of overhead, but it definitely seems like a waste. It seems like Django should not pummel the system with a ton of extraneous queries, even if they're extremely small."
