Making DBCC CHECKDB Go Faster

Speaker(s)Argenis Fernandez 

Duration: 60 minutes

Track: DBA Performance Track

Along with backups, consistency checks are the two most important tasks that DBAs need to perform regularly. Our databases are getting bigger every day, and CHECKDB run times, along with its performance impact to Production systems, keep increasing. In this session we discuss how to improve your system so that you can reduce the time that it takes to run CHECKDB or the individual DBCC CHECK* commands. We will cover topics like DOP, tempdb configuration, trace flags, Resource Governor, and many more. In one of many the demos we will explore a real life example where SurveyMonkey's consistency checks were taken from 7 days down to 6 hours.
