How fast is MenuetOS. Where there any tests? Like: solving a big matrix, or rendering, or compressing files,...?
What are the REAL advantages of not using abstract layers, and doing everything uncontrolled? How much faster is it to write a file to disk, or render some image,....

If you want a speed benchmark of "OS overhead on applications", you could start by porting something like POV-ray to Menuet. My guess is that the performance difference of this will be minimal, as almost all the time will be spent in ring3 code.

For other benchmarks... you'll probably have to write your own stuff to test disk I/O, network throughput, threading, etc. I guess that there, theoretically, could be some gains here - but whether it will beat something like windows NT depends on how well menuet is implemented.
