This.

I've also heard some suggestions recently that storing the global table 
in a VRF uses 2x the space than it would without. I cannot speak from 
personal experience, but you may wish to spend some time researching 
and/or experimenting without that 'feature', also.

But even then, it's only going to come down to how the TCAM space is 
partitioned...
