If you're worried about performance, see http://blog.darknedgy.net/technology/2016/01/01/0/

An example from the linked blog post:

> It strikes me that anti-microkernel sentiment most vocally originates as a sort of tribal affiliation mechanism by Linux users to ward off insecurity.

I think the post would be a better reference and stand a greater chance of correcting common misconceptions if it didn't include so many ad-hominem attacks against those who don't agree with the post's author. As-is, it just appears to be a continuation of a long-running flame-war.

I agree.

Unfortunately, I am not aware of a compilation of misconceptions on microkernels article that's more valuable than this one.

It seems pretty trivial: every hypervisor and/or virtualized system is running a type of microkernel. If it's fast enough for the cloud, it's fast enough period.

I find it ironic that Linux itself is an application running underneath a microkernel.

Running Linux under something lower level is old hat, see RTLinux:

Well, that's not exactly a microkernel, but took lots of inspiration from microkernels.

I take it that you may be alluding to the debate between Torvalds and Tannenbaum regarding microkernels.

The first PowerPC linux for the Power Mac ran under the Mach microkernel [1].

Then there was also L4Linux, which I believe was the first low-overhead virtualization of Linux using the L4 microkernel. Papers demonstrated < 10% overhead I believe, where previous virtualization efforts were somewhat higher. I'd say it kicked off the whole paravirtualization/virtualization craze.
