There's probably some misunderstanding. If some piece of work needs 1
second to do something then it needs this second, no matter where it
runs. If you want it to complete faster then you have to work on the
algorithm or use faster hardware or similar approaches.
When you run some work on the microkernel directly you have more
control over it's execution behavior than you typically have in Linux
but a smaller kernel does not make your code run faster!
