Interface between Java and Matlab potential bottleneck?

I am optimizing a Simulink Model using several algorithms and I would like to test them in terms of speed. The Matlab scripts used for this are driven by java.

The Problem is: I can see the plots of the optimization being done, the algorithms seem to be completed (f.e. because of maximum iterations) but the java console goes on for a very long time, printing the matlab console output. I suspect that the character stream has to be processed and this does not happen faster via the Matlab Java interface. Is there any way to fix this? I don't need the console output, which is why I also already use the following code to perform the function evaluation.

eng.feval(0, "SIMOptimization", NULL_WRITER, NULL_WRITER);

I wonder if it would help to use an evalc() level, something like

eng.feval(0, "evalc(SIMOptimization);", NULL_WRITER, NULL_WRITER);

Good idea, but SIMOptimization is a script and sadly thats why evalc() seems not to work here, or am i missing something?

EDIT: After searching the forum i came to the idea to create a separate script calling "evalc('SIMOptimization');" and java calls this script. And what can I say, it seems to work wonderfully! Thank you very much for this thought thrust.
