This paper presents the experimental study of the performance of L4Linux on top of L4/Fiasco and Linux. Holding the hardware constant and using the different benchmark tools to measure a list of performances in order to give us a global view for performance comparison of L4Linux/Fiasco and Linux which could separately stand for the micro-kernel and monolithic kernel. Our experiments and analysis show the concrete measurement about their performances and in the end we present our conclusions. In Addition through these benchmarks we find some problems and maybe they are new task for the L4 community.
