Software has to be tested from functional and performance viewpoints in order to create products, which fulfill customer demands. The need for testing has led to the development of a plethora of testing tools. Performance measurement of SW latencies on local and distributed SW platforms hasn't yet been completely solved, which is the research problem of this paper. In particular, GPS-based time synchronization and performance of the proof-of-concept has been concentrated on. The approach is to instrument the SW implementation under study, and to collect measurement data with the presented tool. The results indicate a resolution of 590 ns, which can be achieved with high performance reference clocks. CPU processing can be kept lower than 5% even with a high event transmission rate. In addition, the presented GPS synchronization method can be used for other purposes such as data packet time-stamping in network monitoring solutions.
