On my Visual Studio profiler, the following statck is showing up as most expensive, accounting for 17% of total CPU time.  This is a real time market data based app.

>  Infragisitcs.Windows.DataPresenter.RecordManager.ProcessQueuedChangeNotifications()

>  Infragistics.Windows.DataPresenter.RecordManager.OnDelayedChange()

We have our queueing mechanism for propagating propertyChanged notifications to the UI.  Is there a way to turn the queueing off inside the XamDataGrid RecordManager from the API?

Thanks.
