Hi All,
We are migrating SQL server 2005 database to SQL server 2012. We have taken the user db backups from old sever SQL 2005 and restored it on the new server SQL 2012 instance and ran the DBCC updateusage. When I tested simple select statement the new server is taking 30% more time than the older server SQL 2005.
1. Both server has same disk level and database file configuration for tempdb and user databases.
2. SP_configure is also same except the below two.
a. CLR is enabled on the new server, but on old server it is disabled.
b. cost threshold for parallelism is 10 on new server but on old server it is 5.
3. New server has been build with high CPU and Memory than the old server.
Why the new server would be taking more time than older even though it has high server configuration? what else I need to check to identify the issue?
Thanks
Kumar
