流媒体服务器的性能测试和瓶颈分析

摘要

讨论了流媒体系统的各种性能指标和流媒体服务器的平台性能限制之间的关系。我们通过改变下列条件：连接数,并发活动的媒体文件的数量,以及流媒体的编码格式和码流,来测量流媒体服务器的CPU空闲时间,IO等待,内存,网络带宽的变化,找出流媒体服务器的性能指标和制约瓶颈。通过有针对性的提高服务器处理瓶颈的能力,可以进一步提高流媒体服务的性能。%We discuss the relationship between the capability of the stream media system and the perform-ance constraints of the stream media server. In out experiments,we try to change the following environ-ment:the number of concurrent connections, the number of media files opened the format of streaming media and network bandwidth. By measuring CPU idle time, IO waiting time, RAM of the streaming media server,we find out the performance and bottlenecks of streaming media system. Through improving the important capability of media server,the performance of streaming media service can be improved sig-nificantly.
