我想我找到我想要的了。也许你可以让查尔斯代理或者慢慢来。希望能有所帮助。

我会尝试在linux上使用netem。有了它，你可以模拟额外的延迟、损坏、丢包和复制。它甚至可以用在环回设备上。

使用Fiddler在Windows上找到了这个(免费解决方案) http://www.logic-worx.com/index.php/tools-and-apps/fiddler-connection-simulator/

为了模拟一个低带宽连接测试网站使用谷歌Chrome浏览器，你可以去网络选项卡在F12工具和选择一个带宽级别来模拟或创建自定义带宽来模拟。

Take a look at the NE-ONE Network Emulator which allows you to configure bandwidth, latency, packet loss, packet reordering, packet duplication, packet fragmentation, network congestion and many more impairments so that you can create real-world network conditions in the lab. Different impairments can be configured for the up and downlink so you could have a really good uplink but a really bad downlink experience, great for seeing how the app handles TCP queuing because the acks don't come back in a timely manner and the overall latency therefore increases!

这里有一个专门针对游戏开发者的概述视频http://www.youtube.com/watch?v=DwtqlE7LcrQ，但它说明了它的内容。NE-ONE是使用web浏览器配置的，所以它真的很容易安装和配置-你不需要是一个网络专家:-)

有一个硬件版本- http://www.itrinegy.com/index.php/products/network-emulators/ne-one -或者你可以下载在VMware ESXi Server下运行的虚拟设备(软件)版本。虚拟设备可以从VMware的Solution Exchange - solutionexchange.vmware.com/store/products/ne-one-flex-network-emulator下载
