The site optimization settings use the Google PageSpeed module filters. It is installed on the hosting by default and is designed to speed up the display of the page in the browser. The documentation for this module is available at official website.
Website speed is one of the most important factors that modern visitors pay attention to. Site display delays cause annoyance, negatively impact search engine rankings, and reduce revenue for commercial sites. From the point of view of the visitor, the speed of the site is influenced by two main parameters: the speed of page formation on the server and the speed at which the page is displayed by the browser. To speed up the formation of pages on servers, we use modern equipment and fine-tuning software. Also, our clients have access to tools that allow us to speed up the speed of displaying the page in the visitor's browser, just by making changes to the settings of their site.
There are several techniques that can be used to increase the speed of displaying the site in the client's browser:
The PageSpeed module also works over the HTTPS protocol. When the site is configured redirect from HTTP to HTTPS (or vice versa) using .htaccess, there may be problems with the processing of content by the PageSpeed module over HTTPS. To fix the situation, you need to remove the redirect directives from .htaccess and instead enable the required redirect in the site settings.
Caching allows the browser to save a copy of the static file on the visitor's computer and not ask the server for it on a second visit. However, this creates inconvenience to developers, since visitors will see changes in these files with a delay for the duration of the cache. To avoid this problem, PageSpeed provides advanced caching options for images, styles, and scripts. If used in URL static files, a hash of their content is added, which changes when the file is edited. Thus, long-term caching is achieved with the ability to freely make changes.
To configure PageSpeed, do the following:
a-z 0-9 - . _ / *.
To add URL into PageSpeed exceptions, do the following:
To clear the PageSpeed cache, do the following:
To completely disable PageSpeed, do the following:
