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?
Thx
This is expected when the index spans multiple files. Also, the number is
not relevant for heaps (tables with no clustered index).
Hope this helps.
