Abstract
With the rapid development of information technology, the performance optimization of operating system as the core component of computer system is crucial. Linux memory management mechanism is one of the key factors affecting the system performance. This study focuses on the Linux memory management mechanism and performance tuning strategy, aiming to deeply analyze the principle of Linux memory management mechanism, including physical memory allocation, virtual memory management, page cache mechanism, etc., and propose effective performance tuning strategy for the problems existing in the existing mechanism. Through the combination of theoretical analysis and experimental testing, the test environment is built based on different application scenarios, and carries out multi-dimensional evaluation of Linux memory management mechanism. It is found that the memory management efficiency of Linux system can be significantly improved by improving the memory allocation algorithm, adjusting the page cache parameters and optimizing the exchange space use, especially in the scenarios such as high concurrency and big data processing.
