Hi,

As I have mentioned on the list on the past... UPDATE STATISTICS requires lots of slow 
disk I/O and it locks the tables.  Some of our tables 
are large and the lock can last for long periods (30 minutes or longer for a single 
table).  Yes, this is on professional 15,000 RPM SCSI hard 
drives.

My question... I'm assuming that UPDATE STATISTICS is doing is changing some internal 
pagecount or otherwise.  We have 3 servers all 
running with copies / replicas of the same database.  Is it possible that we could run 
UPDATE STATISTICS on only one server and duplicate the 
results to the other two servers?

On a related note, if I use loadercli to populate a database that was sourced from 
"TABLEXTRACT PAGES" - do I have to run UPDATE 
STATISTICS to get it correct - or is that brought over with the extracted table?  The 
UPDATE STATISTICS seems to take longer than loading 
the data itself :)

Thank you.

  Stephen Gutknecht
