Abstract :
Tests for measuring the real time operating system performance belong to the software technology. They give quantitative measures for the most important characteristics and allow the implementer to compare the efficiency of various operating systems. The paper presents a set of simple tests for measuring the real time operating system characteristics. The tests require no specialized hardware, and are based on direct measuring of the duration of execution of sequences of system functions. All tests described in the paper have been applied to measure the efficiency of a distributed operating system QNX. The measurements include the speed of intertask communication through messages, proxies and signals, and the speed of task switching and timer interrupt handling. The results are presented in a series of easily readable tables
