Arrakis is a research operating system from University of Washinton, built as a fork of Barrelfish.

In Arrakis, we ask the question whether we can remove the OS entirely from normal application execution. The OS only sets up the execution environment and interacts with an application in rare cases where resources need to be reallocated or name conflicts need to be resolved. The application gets the full power of the unmediated hardware, through an application-specific library linked into the application address space. This allows for unprecedented OS customizability, reliability and performance.

The first public version of Arrakis has been released recently, and the code is hosted on GitHub.

The performance numbers are very impressive. The other (different but just possibly comparable) operating system is DragonFlyBSD which posted some really quick database performance stats a little while back.
Unfortunately although the two platforms are both benchmarked against Linux; DFBSD uses PostgreSQL whilst Arrakis uses Redis NOSQL.
It would be interesting to compare the two over the same tasks.
It would also be interesting to see whether aspects of each could be grafted into the other for even more impressive gains.
