L4 is a 2nd generation Microkernel, whereas Mach is one of the first attempts. It has better IPC performance (although this is synchronous and thread-id based, with Mach IPC being asynchronous and capability based) , a much smaller code base, and less policy enforced in the kernel. For performance figures, this is a good read: http:// os.inf.tu-dresden.de/~jork/papers/sosp97.pdf otherwise you can read all about L4 here: http://ertos.nicta.com.au/research/l4/ Out of curosity, what advantages does the L4 Microkernel provide over the current one? We've been working on porting Darwin (currently working with the 8.2 source base) to the L4 Microkernel for a while, and now we've just made a release. The complete source is available, as well as a QEMU boot image, and instructions for booting on real hardware. See http://www.ertos.nicta.com.au/software/darbat/ for more details.
