What does it do?
GZIP is a popular and effective compression method that reduces response sizes by 60-70%, vastly lowering response times and improving site performance.
Enabling GZIP compression is a standard practice to provide smaller file sizes which will load faster for your users.
When and how should I use it?
GZIP compression is enabled by default on all StackPath CDN sites. By default, the StackPath CDN GZIP compresses txt, js, html, and css files, and the text/* mime type.
We recommended compression level 6 for a good performance balance between response sizes and the time it takes to compress assets.
