Microkernel Performance: FreeBSD versus Darwin

[Paul Smith]

Theoretically the microkernel of Darwin should create overheads harming the
performance.  Has anybody seen an actual study comparing the performance of
Darwin and FreeBSD?

DEC's Tru64UNIX used a microkernel, but the Alpha hardware was so superior
for its time that any loss of performance could have gone unnoticed.
Similarly Tera runs on supercomputers that can absorb a little extra
overhead.

Does anybody know of any serious benefit arising from the microkernel?  Or
is Darwin simply Steve Jobs' passion to bring back NeXT?
