Socket做代理服务器为什么响应很慢

无奇龙

无论资源多小，下面这个循环都是要执行15秒左右。
while(rBytes>0){        rBytes=IPsocket.Receive(RecvBytes,RecvBytes.Length,0);    strRetPage = strRetPage + System.Text.Encoding.Default.GetString(RecvBytes, 0, rBytes);   }

慢会不会是网速或者是代理慢

这个代理慢，用Fiddler是很快的，人感觉不出来。

守望幸福

1.建议对Main函数、Proxy构造函数、Run函数下断点，调试慢在哪里
2.对可能出现拖慢速度的地方加StopWatch看看，检查慢的原因
