Hi,
I am looking at Django's performance with respect to modifying large
numbers of objects, each in a unique way that cannot be batched. If I make
a simple change to one of my Django models and save(), and then do the same
thing in sqlalchemy, I notice a performance difference of about 48 time
Damn. Missed that. Thanks.

If I return an HttpRedirect() with a relative URL in it, I notice that
