I'd love to see the improvements made on the 1.2 branch ported to the MemPF branch (v2.0).

MemPF seems to work well in OpenSextant but it hasn't been as throughly evaluated. I suspect if Stanbol ports to MemPF, and if Rupert does his measurements as he's done before, it will be more clear through its tests, etc. how well the MemPF does.
