No, not really. I have looked at it in theory and like the idea of
microkernels from a design point of view, but it might have some drawbacks in
UP performance. For SMP the performance difference between micro and
monotholic kernel designs should quite minimal, or even to the microkernel
based benefits due to cleaner design with less global locks.
Normally you don't run anything directly on top of a micro-kernel, but run
applications like Squid on top of a POSIX or similar subsystem on top of the
microkernel.
