Answer 4

你也没说程序里做了什么操作呀
IIS有默认的请求超时、程序池也有内存及CPU的限额设置==

Answer 5

应该不是代码问题吧，该关闭的都关了，以前是用的FCK插件添加视频，现在直接用的上传控件

Answer 6

如果你硬要用http上传，需要修改配置文件里最大上传限制
以及Server.ScriptTimeout = 600;
默认是90秒，设定的时间内没有上传完毕请求将超时，上传失败，这段时间的连接对服务端而言是一种累赘
如果文件过大，建议用ftp并且断点续传

Answer 7

你有监控服务端的负荷吗，比如内存、CPU、出错次数==
假如有好几个人同时在上传呢？
