Matlab RTW and Simulink

Does anyone out there have any experience taking Matlab RTW generated C code and compiling and running on QNX? I have questions about timing. Specifically, it seems that I can’t get a simulation to run on QNX with a frequency smaller than 500Hz. I’m sure a natively written C program could achieve better rates and I’m wondering if the Matlab code introduces too much overhead.

Any and all help is welcome.
