One more thing to keep in mind, you may have statistics on columns that are not in indexes. Make sure those are being updated. Your plan could potentially skip these statistics.

I agree with Igor's post. Here's some info on the trace flag: http://blogs.msdn.com/b/saponsqlserver/archive/2011/09/07/changes-to-automatic-update-statistics-in-sql-server-traceflag-2371.aspx

Thanks Guys for your input,
Igor,
can you please elaborate on ...if you do REORGANIZE on big indexes and then update their stats, then you'd better check the time for only REBUILD them regardless they have #frag<30%

Thanks
