29620	Document possible performance benefits from transactions	WGH	nobody	"Currrently, the documentation says:
> Open transactions have a performance cost for your database server. To minimize this overhead, keep your transactions as short as possible. This is especially important if you’re using atomic() in long-running processes, outside of Django’s request / response cycle.

I think it's misleading, as it sounds like transactions are always bad from performance perspective, and autocommit mode is better. While in fact batching DB operations in transactions can have serious speedup, especially when inserting massive amounts of rows. (of course it may have impact on concurrency, but there ain't no such thing as a free lunch)"	Uncategorized	closed	Documentation	2.0	Normal	needsinfo			Unreviewed	0	0	0	0	0	0
