Method, system and device for judging stack layer optimization

Abstract

The invention discloses a method for judging the optimization of a stack layer, which comprises the following steps: receiving input test information; determining a calling command, a stack layer to be tested and a calling layer according to the testing information; a first invocation result being virtually generated in the invocation layer according to the invocation command, and first performance data being obtained according to the first invocation result. A second invocation result is virtually generated in the stack layer to be tested according to the invocation command, and the second invocation result is returned to the invocation layer, and then the second performance data is obtained according to the second invocation result. According to the first performance data and the secondperformance data, whether the stack layer under test needs to be optimized or not is determined. The present application performs IO testing on each stack layer in an IO stack by returning virtual data, and further analyzes the influence of each stack layer on the system IO, so as to point out a direction for optimizing the IO performance of the system and reduce the range of IO tuning. The invention also provides a system, a device and a computer-readable storage medium for optimizing and judging a stack layer, which has the beneficial effects mentioned above.

Description

technical field [0001] The present application relates to the field of IO performance, and in particular to a method, system, device and computer-readable storage medium for stack optimization judgment. Background technique [0002] Computer system IO performance tuning is a problem that IT equipment manufacturers and network companies cannot avoid. From simple parameter tuning of general computer system IO performance to changing the system-related IO architecture to adapt to relevant scenarios, the purpose is to hope that the system's IO performance can meet the user's IO performance requirements. [0003] There are two main reasons why IO performance optimization is a difficult problem for IT equipment manufacturers and network companies: [0004] 1) The IO path of the computer system is very long. Even if network access is not considered, the IO path of the desktop linux system may include the following layers: user application → system call → virtual file system → file...

AI Technical Summary

Problems solved by technology

A system that satisfies a certain scenario may not be applicable at all when switched to another scenario, and serious data loss may occur

Therefore, if system tuning wants to achieve satisfactory tuning results, it is necessary to have a good understanding of the performance of the entire stack layer of the system, and only using relevant tools for test analysis may not be able to obtain real data, and thus cannot correctly analyze system performance bottlenecks
