Who's going to make seL4 perform comparably to Linux?

Not sure about the unhackable claims part but it seems at least to be an interesting project. This is a formally verified L4 derived micro-kernel, its code is open-source (GPL2, BSD).Homepage: https://sel4.systems/Github: https://github.com/seL4/seL4Related course (already posted on HN i think but can&#x

> This whitepaper provides an introduction to and overview of seL4. We explain what seL4 is (and is not) and explore its defining features. We explain what makes seL4 uniquely qualified as the operating-system kernel of choice for security- and safety-critical systems, and generally embedded and cyber-physical systems. In particular,we explain seL4’s assurance story, its security- and safety-relevant features, and its benchmark-setting performance. We also discuss typical usage scenarios,

It's there an OS built around Sel4?
