fiddler-010-Network delay Application Tips-analog low-speed environment

In daily network testing, it is often necessary to test scenarios where the network is out of time or in poor network transmission rates, while at the same time we sometimes have limited resources to test some of the limitations in a variety of real-world Network (2G\3G) environments. In fact, Fiddler has provided a similar function, by limiting the transmission rate of data, approximate imitation of various network scenarios, although not accurate, but indeed a very good network environment simulation means!

Speed limit is important for front-end (web, app) testing and development, and is a necessary part of testing. Because the developer's machine general configuration is very high, and in the local or corporate LAN debugging procedures, then the network situation is undoubtedly very good, it is difficult to simulate the actual use of the user situation, when the speed is very slow, the webpage download the required resource files (JS\CSS, etc.), will be very slow, Page rendering is likely to be problematic. At this point, of course, we would like to see the user interface is rendered first, rather than let the user see a blank. At this time, the network speed limit can be very convenient for similar situations to do performance tuning and optimization. A fiddler is a speed limit that is achieved by delaying the request or requesting a response.

So, how is fiddler specifically implemented? Continue below:

Enable the analog low-speed environment path "rules/performances/simulate Modem Speeds", when enabled you will obviously feel that the speed of the network has slowed down a lot, especially when the resource file is relatively large.

What, still not enjoyable, or too fast ... Zoom in-----speed limit! Speed limit! Speed limit!

Set the speed limit path as follows:

or shortcut key "Ctrl + R" directly open the Fiddler Rule Script page, find the following red box shows the content

The time unit corresponds to milliseconds, which is time-consuming for each upload/download of 1KB. The calculation settings are required for the desired test and development scenarios.

PS: After setting "Rules/performances/simulate Modem Speeds" will uncheck the default, you need to enable it again, the setting will take effect. Of course, you can also cancel the cache, just tick "Disable Caching".

At this point, fiddler-010-network delay Application Tips-the simulation of low-speed environment successfully completed, I hope this article can give beginners Fiddler you a reference.

Finally, very grateful to the pro-stop, I hope this article can be pro helpful. Warmly welcome the kiss to discuss together and progress together. Thank you so much! ^_^
