I''m not sure if it''s known to be very fast - it''s not
going to fully optimised
in the 3.0 release, AFAIK.

Are benchmarks running slower than expected on it?  (I know you can''t
publish
them but they might be interesting to look at).  Bear in mind that the QEmu
display device we''re using is sluggish even under QEmu.
