Problems solved by technology
Currently, the performance bottleneck measurement schemes of the Linux operating system mainly include kernel tracepoints, kernel probes, Perf Event, and kernel function sampling. Since these four schemes do not form a unified whole, sometimes even when these schemes run together It will also interfere with each other and affect the final measurement result. Therefore, we cannot only use the existing performance bottleneck measurement scheme on Linux to measure the performance bottleneck of the Linux operating system. We must design a simple and targeted A Performance Bottleneck Measuring Scheme for Linux Operating System

The present disclosure relates to an analysis method, system, device and storage medium of an operating system performance bottleneck. The analysis method includes: adding a hook function in the kernel program of the operating system; obtaining the kernel execution path of the kernel program through the hook function; Set the first sampling point in the first sampling point, and obtain the number of instruction cycles of the kernel execution path collected by the first sampling point; analyze the instruction cycle number of the kernel execution path collected by the first sampling point, and determine the existing kernel execution path according to the analysis result Code snippets for performance bottlenecks. In this analysis method, the kernel execution path of the kernel program is obtained through the hook function, and the number of instruction cycles of the kernel execution path is collected according to the first sampling point to determine the code segment of the performance bottleneck in the kernel execution path, so as to realize the accurate measurement of the performance bottleneck of the operating system. Ultimately eliminate the performance bottleneck of the operating system.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an analysis method, system, device and storage medium for operating system performance bottlenecks. Background technique [0002] As an open source operating system, the Linux operating system is developing very rapidly at present. Many different versions have been developed, such as redhat, suse, ubuntu, etc., and are widely used in the production server systems of governments, e-commerce, enterprises, etc. After development, it is integrated into various computer hardware devices. [0003] Since the kernel of the Linux operating system is a macro kernel and is widely used in the fields of servers and embedded systems, existing servers pursue high-density computing, system throughput and computing diversity. In order to make the Linux operating system have real-time characteristics, it is necessary to accurately measure the performance bottleneck of the operating...
