Analysis of Linux Kernel’s Real-Time Performance

The Linux OS is used in various devices, but not in real-time fields mostly. The real-time performance of Linux kernel is analyzed between the 2.6 and 2.4 kernel, using the LmBench tool. A test method is introduced to compare the real-time performance, based on two preemption strategies. It is concluded that the real-time performance of the 2.6 kernel has been greatly improved, which can basically meet the requirements of real-time systems.
