i've got Media Prioritisation turned ON with my Vrgin SuperHub2 and I am getting 95Mbps, and when i turn it OFF - i still get 95Mbps.
however - i am still losing over 50Mpbs because when i connect my laptop direct to the Virgin SuperHub2 i am getting 152Mbps.
there must be something on the Virgin SuperHub2 that realises it is a 3rd party router attached and it throttles it back - for some bizarre reason???
