Auto Create Stats

Is it a good idea to have Auto create stats and Auto
update stats ON in a database
Does it slow down performance while loading large amounts
of data
SanjayHi Sanjay
No, the updating of stats does not happen during a load. When you run a
query, and SQL Server notices the stats are out of date, then it will auto
update them.

Nothing is free, so Auto Create Stats does cost something from the server.
However, I understand that it tries to do that work during low periods and
stay out of the way of other work. And remember, statistics that are not in
sync with the data can cause the optimizer to guess wrong.
There is a discussion of the issues at:
