What we really want to do, alongside capturing good benchmark- and more permanent data with WebPageTest, is interact with and inspect a site slightly more realtime. Network Link Conditioner. In there, you should find a tool called Network Link Conditioner. If you’re used to Chrome’s Network tab then, well, I’m sorry.
With entrance into the industry being so easy and lack of proper benchmarking (Note: this is somewhat contradictory to point 2, but more on that later) around what makes a good designer, software engineer, or product manager, we’re forced to face the facts that it’s a recipe for poor quality products. Community is everything in the industry.
The gotcha here is that, if your mobile experience isn’t optimized for various devices and network conditions, these customers will never appear in your analytics — just because your website or app will be barely usable on their devices, and so they are unlikely to return. A performance benchmark Lighthouse is well-known.
A video with large dimensions or a high bitrate will take longer to download and will require a higher speed network to play back smoothly. This leads to longer startup times, and if the network cannot supply the video fast enough, the video will stall during video playback. There is a solution though! Large preview ).
The resource loading waterfall is a cascade of files downloaded from the network server to the client to load your website from start to finish. It essentially describes the lifetime of each file you download to load your page from the network. You can see this by opening your browser and looking in the Networking tab.
In this case, we are not going to be talking about infrastructure services, such as a cloud computing platform like Microsoft Azure or a content distribution network like Akamai. And JavaScript can certainly make requests for additional network resources. Sometimes, the visitor’s browser itself can be the origin of network activity.
In this case, my website is “slow”, even when served on 4G networks. Because service workers exist outside of the web browser and are not contingent on the speed of the user’s network, they load cached content for visitors more quickly. second benchmark for mobile loading. seconds too long. Which I wholeheartedly agree with.).
Today, the website is much faster and ranks highly in various showcases and benchmarks. Many of them are covered in CSS-Tricks’ helpful overview , and Smashing Magazine offers a great PDF checklist. The waterfall of network activity helped a lot here, but so did thinking of user flows. Large preview ). Large preview ).

If you don’t have a device at hand, emulate mobile experience on desktop by testing on a throttled 3G network (e.g. Moto G4) on a slow 3G network, emulated at 400ms RTT and 400kbps transfer speed. 300ms RTT, 1.6 Mbps down, 0.8
