Turn on compression to optimise your site
Enabling compression for your web content means that the server compresses your content before sending it across the internet to visitors. This can often yield a significant performance benefit and we strongly recommend turning it on.
You can find the settings within cPanel > Software > Optimize Website
To enable compression for all content simply ensure the Compress All Content radio button is selected and click Update Settings.
Please be sure to thoroughly check the functionality of your site after making this change to ensure everything still works and looks as it did before.
If you find an issue you can either revert to Disabled, or you can specify which MIME types to compress, leaving out whichever type is causing the problem. Images file formats (e.g. .jpg and .png) already compress data, so should not be added to the specified MIME types field.
