The problem is that to really do an unbiased test you would need two
*identical* teams, and ask them to make two OS's, for the same
destination machine, one using a microkernel architecture, and the other
using the monolithic approach. This is in practice not feasable and the
publications on the subject can only shout: "look: I've got a good
performance using a microkernel", "we've got very good performance using
a monolithic aproach" or "it only took us X months to implement this OS"
If people did benchmark their OS's they wrote the OS for one architecture,
and adapted it to test the other. This adaptation will naturally degrade
performance, and show that the designers were right in the first place.
Anyway, anybody have an opinion about the fact that code for printf
is included three times in the Minix OS when it runs (once in the
kernel, MM and FS)
