Auto Create Stats & Auto Update stats

I've inherited a server where auto create stats and auto update stats have b
een turned off. There is a weekly job which executes Update Statistics on e
ach table with the norecompute clause. In looking at traces I'm seeing quit
e a few missing statistics
entries.
When is it appropriate to turn off auto create stats?Peter,
as I understand it, if you've just created a table and are loading it with
loads of rows, you might disable the creation of statistics because the
performance overhead is more than you can afford. Likewise if the table
already exists with statistics and requires loading, you might run
sp_autostats or the UPDATE STATISTICS command with the WITH NORECOMPUTE
option. However, this is only a temporary measure and once loaded it is
normal to have it auto updating, or else incorrect query plans may result.
