Hello everybody,

First: SQL Server 2000 sp3a, HP cluster server, MS 2003 server,
database recovery model simple

Torn page detection:
When I have this option turned on, processes conected with updating and
writing in database, was MUCH more slower, than if I've this option
turned off.

It seams to me, that when this option is turned on, the sqlserver is
much more slower by any operation connected with writing, than without
this option.

This option is required for ensurance, that the data are written
properly on the media.
My question is:
if I have my database running under cluster, with RAID hd system, which
contains write cache, with additional checking, that the data will be
written correctly, is it necessary for me to keep this option turned
on?

Auto shrink:
When it is turned on, does it affect performance?
Personaly, I don't think so, but somebody is insysting on it, and I
would like to have an information from independent source about that.

Best regards

Matik
