we have an application that throws a kind of c+±timeout-exception
(derived from std::exception). if the exception is thrown, we can see
with tracelogger that it takes about 100us to throw and catch the exception.
the cpu of the system is a transmeta-crusoe at about 660mhz - on a
celeron maschine it takes only about 60% the time …
the code is something like this:
there is no nested function-call an nothing to implicity delete, there
isn’t “much stack to unwind” - but why takes is so much time ?
we use gcc 3.3.5 and neutrino 6.3.1 …
another “problem”: it seems that the throwing process isn’t preempted by
higher-priority processes while the exception is thrown/catched ?
i think we do something completly wrong - but i have no idea what ?!?
