Windows 2012, SQL 2008 STD.
I have a database of 60GB size, not too big.
I am trying to rebuild index and update statistics using SQL SMSS Maintenance Plan.
Rebuilding index went smooth, took less than 2 hours.
Now the next step is to update statistics.
I chose 'Column Only ' (because RebuildIndex does updating statistics on indexes as I read) and Full Scan option (because I saw a few report, there's not much difference between Fullscan and more than 25% sample rate).
The update statistics just take too long. Right now it's been running 4 hours, still keep going.
I read online, some guys having much bigger database like more than 500GB takes only 40 minutes or around.
My database takes too longer comparing to what I read online.
Some suggests to create clustered index, but I'm not allowed to change the database structure.
Why does my database take too long updating statistics? I can't find answers. Is there anyway to identify and fix the problem?
