ABSTRACT

This report is a real-time performance and robustness evaluation of the QNX v6.1 RTOS from QNX Software Systems Ltd. Aside from the standard performance tests, the test suite has now been expanded with several stress tests. The evaluation report covers the following topics:

- Theoretical study of the architecture, API, tools, development method, ...
- Interrupt Handling
- Thread Handling (thread creation, thread switch latency, ...)
- Synchronization mechanisms (semaphores, mutexes, priority inversion, ...)
- File system performance
- Network stack performance
- Advanced Interrupt Handling (two simultaneous interrupts, nested interrupts, maximum sustainable interrupt frequency, ...)
- Memory leak detection
- Real-time performance monitoring with varying system loads
