Over the last year our DBCC Check DB process has jumped from ~ 8-9 hrs to. ~ 25 hrs. I decided to breakup the maintenance plan into separate sub plans to identify where all the time is allocated as all our DBs are generally same size bar 1.Subplan #, DB size1. System DBs grouped2. 1 x 300gb DB3. 1 x 250gb DB4. 1 x 250gb DB5. 1 x 900gb DB6. All other DBs (approx 100-200gb total)I found that #5 (900gb DB) takes ~19 hours while the others take ~ 5-6 hrs in total.I don't know if 19hrs is normal or not due to size / data etc and i have nothing to worry about as long as it doesn't throw errors.Does anyone have some advice or tips to help identify why so long or just previous experience that its normal.
