At work, it is sometimes necessary to simulate the slow network speed of users to further test and optimize the product. The more common ones are: Fiddler,NetLimiter,Network Delay Simulator (which is simple to use and works well) is introduced later.

First understand the differences between these three tools:

Fiddler free software. The function of simulating network speed is relatively simple (Rules-- > Performance-> Simulate Modem speed), and there are few options. Fiddler only slows down the bandwidth and does not introduce packet loss, and the waterfall diagram of (Http watch or Firebug) test results is incorrect because of the number of concurrent connections in the browser. Although it has this function, it is generally used less. The highlight of fiddler is on the other hand-- the blog post "about the utility of tool Fiddler"

NetLimiter sharing software, you need to register yourself. To be exact, it is a network traffic control software, through which you can directly control the access of each program to Internet and the distribution of traffic.

Network Delay Simulator free software, download address. The most powerful of the three, monitoring the network traffic between Network Interface Card (NIC) and TCP/IP stack can simulate delay, bandwidth and even packet loss rate, and more accurately simulate the slow network environment.

The setup is also simple and convenient: delete all default production flow, create flow under the current network card, type and click File-save;. If you want to simulate packet loss, fill in the packet loss rate.
