问题 We have deployed SQL Server 2012 Enterprise and we have performance issues: same data (backuped from our SQL Server 2005 Enterprise and restored on 2012) test script of 3200 sql SELECT statements We do tests using Management Studio: results as plain text results in a file On same computer: 2005 : 15 sec, 2012 : 2 min 2005 : 14 sec, 2012 : 30 sec Even with a more powerful computer, 2012 is still slower than 2005.
