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.

Cheers,
Mark
