This paper discusses the different benchmarking tools used to evaluate the performance of Linux and their suitability for evaluating Real Time system Performance. The importance of using Statistical Methods as well as defining absolute hard limits is presented. The author will then present an Open Source Test and Evaluation Suite toolkit which rapidly allows system performance to be monitored and… calibrated in a manner to allow a user to define the relative merits of each proposed system. The toolkit can easily be adapted to different operating systems and different environments but still allow results to be compared against each other. Users are encouraged to make use of the toolkit to test their own configurations. Extensions and additions to the toolkit will be discussed. The paper will present results obtained from a number of different Operating Systems on a number of different hardware platforms.

Finally the other requirements that make up a useful Real Time Operating System will be presented. These include reliability, ease of programming and robustness. A number of different approaches to A number of possible ways for measuring. The methods to evaluate the Real time performance of a system are quite different to the tools used to monitor the absolute performance of the system. The requirements for a test and evaluation package are presented. The special needs of Real Time applications are discussed.

The author has developed a set of tools to rapidly evaluate different configurations under different operating conditions.
