You will need to perform this critical task (updating statistics) as often as your data skews.NOTE In high-volume environments, you can update statistics on a restored database, and then import them into the production server using the optdiag utility, but that’s a lot more work.Of the 23 minute Maintenance Plan, Updating the Statistics takes a staggering 13 minutes.During this 13 minute period, access to the database is blocked (or at least, replication from this DB to our others is paused).this solution only rebuilds/reorganize and updates what is needed this way you might shortenthe time your maintinance plan takes and also save a hole lot of log space.. In your original post, you said that users are seeing a performance degredation due to this maintenance plan.Is there no other time to run this maintenance plan? I see that your plan encompasses index reorganization, when are you rebuilding indexes?

This seems like the kind of thing we should do less frequently than every day.PS: Whatever the difference may be, I would not use sp_updatestats as the mechanism it uses to update stats is not good, why should i update stats for table if just one row has changed and I have 100K rows in table, it will just consume resources and cause more issue.EDIT: If you want to update stats selectively and do not want to run sp_updatestas use below query to filter out outdated stats.To do this, it checks a histogram that identifies the data distribution, and uses this information to determine join orders, index selection, and more.You might think that the server would keep this information up-to-date, but because of the resource cost, it does not.
