We have updated to our new server. windows server 2008 to windows server 2008 r2, but our sql server is 2008 only in both the servers. but in my Old server (win 2008 ) any query it was taking 30 min, but the same query is taking 2 hrs in new server (win 2008 r2), and the new server is high configuration server.
In both the servers same Data types, and indexes are same only. we have also cross verified all the setting of SQL server with old server and new server both are matching.
please find the new server configurations.
