Sorry, yes have tried it, I am still seeing a negative perofrmance
difference with the setting on 0 but the gap is greatly reduced and
its something that is a lot more acceptable, at most it has been 10%
worse then if left on auto or set to a value.  Let me know if there is
any specific types of tests you want doing.
