Where would you recommend working to get better performance?  At one time the 
pmap_* stuff was a mess, and that was expected to be improved.  And I note 
that you did some work on it, so is it safe to assume that pmap is not a 
problem any more?

Are there other areas that need work?  (I know that an RPC will never fly 
because of the memory speed)  I note from the TODO that things like irq 
delivery need optimising, there's other things in there as well that may be 
worth looking at.

Is the best way to find out to get a profiling kernel, and put some load onto 
it? (first twisting the machine/asm.h ENTRY macro to do profiling info) 

Cheers,
