ComboStrap - Perfomance

performance is how fast your page will be perceived by your user from the moment they click on a link until they see the resulting page.

Google has a more detailed definition of what performance is and gives you a performance score along with performance metrics via the lighthouse product.

Below is a run of the home page of this website with the lighthouse website version. Note that our web server is running on a small machine with only 2 cores from Canada.

All published stylesheet (bootstrap and bootswatch) are served by defaut from a CDN

If you are using only ComboStrap, you can even disable the Dokuwiki Stylesheet for public user with the disableDokuwikiStylesheet configuration

The size of a web page served to the public (user not logged in) can be optimized with the CSS optimization module

We preload stylesheet that are non critical for rendering. For instance, the stylesheet used for animation are preloaded and added to the page at the end.

All Javascript file are served from a CDN and are deferred (loaded at the end) because they are not needed for the first rendering.

If you only depend on the ComboStrap plugins, you can even disable the backend javascript.

Caching is done by default for all content based process (from page to image).

For more information, see the page: Cache Management

We follow the Google best practices on image

All images are lazy loaded by default. It means that they are loaded only when:

• they are on the screen
• they are going to enter in the screen.

All raster images (jpg, png, …) are also automatically loaded with the appropriate sizing.

If a page contains an big image (say 2400px), this image will be resized and served to 300px on a small mobile screen.
