DBCC DBREINDEX

After we run a dbcc dbreindex for a specific table, we have noticed a huge
drop in, Logical Scan Fragmentation and definite performance improvements.
However, Extent Scan Fragmentation still seems to remain quite high, in most
cases over 50%.
Is there any reason for this?
ThxThis is expected when the index spans multiple files. Also, the number is
not relevant for heaps (tables with no clustered index).

Hope this helps.
