摘要

Linux操作系统用于各种设备，但大多不是实时领域。利用LmBench工具对2.6和2.4内核的实时性能进行了分析。介绍了一种基于两种抢占策略的实时性能比较测试方法。结果表明，2.6内核的实时性有了很大的提高，基本可以满足实时系统的要求。

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.
