This test will check whether your website (and ultimately the server your website is hosted on) has Gzip or brotli enabled by connecting to your domain and requesting the necessary information. Next to that it will also give you some additional information, like the file size of the original version of the web page you test and how much you (may) benefit from using Gzip compression.
Since a compressed file is much smaller in file size (bytes) compared to the original web file, the website will need less time to fully load. Use the waterfall in our page speed test to see the percentage with which each of your website's files are being compressed.
Go here for a detailed guide explaining how to enable Gzip and for more information about Gzip in general.
Brotli is an open source data compression algorithm. In the majority of cases Brotli can compress files to a smaller size than Gzip can, it is therefore generally a better compression method compared to Gzip. Brotli also decompresses files faster in comparison with Gzip.
At the moment Brotli is supported by all major browsers but not all browsers support Brotli yet. If you want to use Brotli you can configure your server to automatically switch between Gzip and Brotli depending on the browser your visitor is using. We will have more on that very soon!
