Abstract: In order to solve the problem that the performance of network server cannot be analyzed in relatively complex situations of number and status, the authors proposed a method of server performance evaluation based on queuing network. This method could effectively reduce the time and space complexity and make performance analysis of server more accurately and efficiently. The experimental results show that using this method to analyze server performance and optimizing the server program by the results can make good use of system resources and improve server performance.

摘要： 针对网络服务器在用户数量和状态相对复杂情况下无法对服务器性能进行有效分析的问题，提出了一种基于排队网络的服务器性能分析方法。该方法可以有效降低时间复杂度和空间复杂度，使服务器性能分析更加精确，效率更高。实验结果表明，利用该方法对服务器性能进行建模和分析，并根据分析结果对服务器程序进行优化，可以达到合理利用系统资源、提高服务器性能的要求。
