Well, i made some shortcuts, like removing fallback handler and it
improved a bit.
I checked everything thoughoutly, and since performance degrades
linearly with each introduced message send,
i don't think its because of bogus code.
The overhead is because we using interpreter to switch processes:
 -removing process from a list
 - adding process to a list
etc etc.

Of course, i could make an additional prims to speed things up for a
little, like doing
  LinkedList>>removeFirst:
  LinkedList>>addLast:
primitively.
But i wouldn't care about it now. I want to explore the real benefits
of having scheduling logic at language side - like reimplementing
Delays, adding nicer process termination procedure (see my other
thread) etc.
