Now I found the answer why the cas-server is that slow. The Problem is
that the cas-server is working only if called by
fileDescriptorManager.process(). This is called by a Timer. If I call
the fd-manager all 50ms all sync reads are 70 times more slow as a read
from a IOC variable. If I call it all 5 ms this factor is 14 times!

That means on a more sophisticated operating system as vxWorx and a
processor involved in more than answer epics requests it will be
impossible to achieve the same response times.
