Performance comparison of Single Board Computer: A case study of kernel on ARM architecture

Due to increase computer hardware technologies, software developers are more focusing on to developing embedded operating system. GNU/Linux becomes a common operating system widely use in embedded technologies. In this paper, we report performance results on a TS-7800 Single Board Computer with different version of kernel that has been released by hardware provider. We compare the performance between operating system with the latest kernel given by hardware provider, Linux kernel (2.6.34) and the previous kernel (2.6.21) Our results indicate that the new kernel has better performance in kernel benchmark, more bandwidth and less latency. In other experiments we found that the results are almost the same and in some cases the kernel (2.6.21) has better performance than the kernel (2.6.34).
