The Research of Performance Test Method for Linux Process Scheduling

摘要

Performance test plays a fundamental and irreplaceable role in the field of software test, especially in guaranteeing the quality and reliability of an operating system. The performance of the process scheduling subsystem directly affects the accuracy and stability of the whole operating system. Linux operating system vendors execute performance test almost in every period of the Linux operating system research and development to enhance their products' competitiveness. However, the lack of methods and tools for the Linux process scheduling performance test has caused great difficulties for Linux operating system vendors to evaluate and tune the Linux kernel performance. Therefore, in order to solve the issues mentioned above, this paper, based on the analysis of Linux process scheduling mechanism, proposes a Linux process scheduling performance test method, implements a Linux process scheduling performance test tool as well, and finally validates the tool experimentally.
