Hi all,
I just did a DBCC INDEXDEFRAG on all tables that was showing up bad fragmentation. I have been monitoring the buffer cache hit ratio of this server for the past 2 days. For the last 2 days the buffer cache hit ratio was 99.8.Now after I did the defragmentation the buffer cache hit ratio went down to 99.0. Did DBCC INDEXDEFRAG did that? Will it come back to 99.8
Thanks ,
LN
