"An RTOS (Real-time Operating System) will sacrifice performance to achieve determinism (low latencies). Several key features to an RT system usually come with a performance cost. A non RT system will perform 99% of the time faster than an RTOS. But all it takes is that one time to miss a deadline to make an RT system crash. An RTOS may be slightly slower, but it will not have those outliers that a normal desktop system would have."
