Disk I/O and Buffer Performance Analysis of Broadcast Server

The special broadcast server of TV station requires owning excellent quality and performance of broadcast. According to the (s,S) strategy, the authors propose the relation of between read buffer, multiplex buffer and program number, data velocity, disk performance, and ASI buffer. The experiment result shows that the read buffer and multiplex buffer will work better on a suitable buffer size range. Base on this result, we can optimize the server resource allocating.
