Google publishes the browser benchmark software "Web Latency Benchmark"

The performance demanded of Web browsers has increased steadily,Google DriveOffice applications like spreadsheets and documents can be created on the browser likeMind map creation, AndMap displayIt is no exaggeration to say that it has already exceeded the category of "web browsing software" already. According to multifunctionalization, the performance demanded of browsers is getting higher, but we measure the speed of reaction of such a browserWeb Latency BenchmarkIt is open to the public.

As JavaScript benchmark software, it is released from GoogleOctane 2.0There are, however,Web Latency BenchmarkIndicates the browser reaction itself "Latency(Latency) "and"junk(Jank) "is a feature of measuring two points.

◆ Latency and junk
Whereas JavaScript indicates the computation speed inside the program, latency and junk are contents showing browser reaction speed / sense of crowding.

This is the state of latency. The left is following the movement of the mouse, while the right is moving behind it.


And here is the state of junk. In some places it is possible to see how the character part can not follow the movement of the mouse cursor and repeat the jump.


This kind of phenomenon is actually part of the user's eyes, which is one of the factors that greatly affects the lightness of machine operation. It is a feature of Web Latency Benchmark to evaluate not only the performance inside the machine but also the visual part.

◆ Download and use it
I actually used this Web Latency Benchmark. Download the file according to the OS you are using from the link at the top left of the website.


Click "Save file".


Launch the downloaded file.


Click "Execute".


The browser opens and the home screen of the benchmark is displayed, so click "Click here to start the test" to start the test.


The test is completed in about 30 seconds and the result screen is displayed.


Items tested here are responses to inputs to the browser performed in the program and rendering processing using the screen shot API. The test uses a server for latency measurement programmed with C / C ++ and a page for benchmark written in HTML / JavaScript.

In addition, it seems that a forum on the results of this Web Latency Benchmark benchmark has already been set up abroad.
