Subject: Re: Central vs. Expanded Storage - current recommendation

please make 20% of your storage ExStore.  This only matters if you are storage constrained, so benchmarking differences when there are no constraints will not show a difference.  When you become storage constrained, the 20% ExStore will easily show better performance.
