The Muen Separation Kernel is the world's first Open Source microkernel that has been formally proven to contain no runtime errors at the source code level. It is developed in Switzerland by the Institute for Internet Technologies and Applications (ITA) at the University of Applied Sciences Rapperswil (HSR). Muen was designed specifically to meet the challenging requirements of high-assurance systems on the Intel x86/64 platform. To ensure Muen is suitable for highly critical systems and advanced national security platforms, HSR closely cooperates with the high-security specialist secunet Security Networks AG in Germany.

The webpage contains instructions for building the kernel yourself, for installing it in a virtual machine, and for running it on real hardware.

You're talking about a claim from the 90s. Microkernels certainly did have performance issues with single core 32-bit x86 architectures. This is where most of the testing was done to "prove" this claim. Modern architectures have a register file, which makes context switches cheaper, and many, many more cores, which makes multithreading kind of important. Monolithic kernel designs find it hard to distribute kernel-based drivers across cores.

I'm not saying Microkernels are definitely (comparatively) faster now, but that the conditions are very different, and the tests need to be redone under modern architectures.
