Sadly, this was too good to be true. I'd messed up the test environment and the 25% is Ubuntu's python verses the one from OE. Ubuntu's uses PGO whereas ours does not which is likely where the speed comes from. The patches in this series do give a small speedup, but its more like 0.5-1%. Shows that PGO is likely worth investigating further though.
