Fiddler 限速

首先，rules
快捷键，ctrl+r
就会出现一个文档

然后
        if (m_SimulateModem) {
            // Delay sends by 300ms per KB uploaded.
            oSession["request-trickle-delay"] = "300";
            // Delay receives by 150ms per KB downloaded.
            oSession["response-trickle-delay"] = "150";

修改这个地方
send是上传，reveices是接收
修改好了之后保存，
需要到rules选择中勾选一下preformence
