The Fragmentation Index (FI) is the percentage of one minute periods of sleep vs. all periods of sleep during the sleep period. The Total Sleep Fragmentation Index (SFI) is the sum of the MI and the FI Sleep Fragmentation was added to ActiLife 6.12. If you created an index with a fill factor of 60%, the page would be around 60% full, etc. Total fragmentation. This property displays the total fragmentation percentage. This indicates the numbers of pages that are not stored in order. If this percentage is above 30%, I usually will rebuild the index to reorder the pages. Average row size The straight-forward way of getting the fragmentation percentage of an index is from the Fragmentation tab of the index Properties window.

Not like this embarrassing page that was somehow updated in 2017, which still tells you to reorg at 5% and rebuild at 30% fragmentation, like your data is still on a drive that looks like a record player and might still start making a clicking noise when it fails. If avg_fragmentation_in_percent > 5% and < 30%, then use ALTER INDEX REORGANIZE: This statement is replacement for DBCC INDEXDEFRAG to reorder the leaf level pages of the index in a logical order. As this is an online operation, the index is available while the statement is running.

You should reorganize an index when the fragmentation is roughly 10%-40%. So healthy index is basically less than 10% fragmentation, little bit less than 10% perhaps. Bad internal fragmentation (having lots of free space on the pages) means the index is bigger than it needs to be. Instead of our phone book having 1,000 pages that are 100% full, we might have 1100 pages that are only 90% full.
