online index rebuild Problem

Hi

Please advice whether i have to do update stats after i do online index rebuild

I use Alter index with (options as below)

ONLINE = ON

SORT_IN_TEMPDB = ON

STATISTICS_NORECOMPUTE =OFF

Should i be doing update stats after this online index rebuild?

After doing online index rebuild when clients connecting to DB the Response time has increased ..

During Online INDEX REBUILD page file usage rises from 3 Gb to 10 GB and stays at 10 Gb even after online index rebuild

i have no idea on this ..

pls Advice ...I Need help..........................

Thanks in advance

By rebuilding the index, the default behavior of SQL Server 2005 is to autoupdate statistics

So no extra work is needed by you

Pagefile is increased, then check the memory settings on SQL Server.

Also if there are tables with frequent inserts and updates then its better to schedule an intermittent UPDATE stats for optimum performance.
