摘要： 基于实验网中的一组测试数据，分析网络背景流量、服务器CPU负载和文件大小对FTP协议性能的影响。实验结果显示，网络带宽、背景流量从根本上限制了FTP协议的性能，CPU负载在较高水平时才会影响FTP协议性能，文件大小与占用的网络、服务器资源有关，也会影响FTP协议性能。

Abstract: Based on the measuring data collected on experimental network, this paper analyzes the effect of background traffic, server CPU load and file size upon the performance of FTP protocol. The results show that bandwidth and background traffic fundamentally constraint on FTP performance, CPU load impacts FTP performance only when it is relative heavy, and file size may affect FTP performance since it is related to the occupied network and server resource.

Key words: FTP protocol, performance measurement, delay, CPU load
