Do both instances of SQL Server have the same memory allocation?
In SSMS
- Right-click on the server name and select 'Properties'
- Select the 'Memory' option.
- There is a 'Maximum server memory (in MB) section.

Hi,

Did you manage to check the SQL Server max memory parameter in both instances?
Were they different?
If so, were you able to make the parameters the same and re-test?

It is due to the page and object batching improvements that came into SQL Server 2012.

Although there was a CU in 2008 R2
