Thanks Rob / Mark, I´m preparing a presentation based on SAP´s K21 Paper in order to show them the benefits of 15.7.
The only problem that we have it was with sp_sysmon and 'enable monitoring' on. Technical Support contact me to say that it was solved in SP 100 so we now are applying it to DEV enviroments. They are very helpful with us to solve this things as soon as posible.
Thanks, the answers are very helpful!!
