Here are new features incorporated in the new Themify framework to achieve fast loading.
Lazy Loading
The lazy loading technique displays all media (images, videos, sliders, iframes, etc.) and component scripts to load on demand (ie. they are only loaded when the element is in the viewport or is in use). Because the files are only loaded on demand, it makes the initial page load much faster.
With the old version, all images and scripts were loaded on page load. For example, if the page size is 2.4mb it might take 1.5 seconds to load. With the new version, the initial page size would be reduced to 1.1mb and average load time to 500 milliseconds. The new version can be 50-70% faster than the old version.
WebP Image
WebP is a new image format developed by Google which can reduce image size up to 50-90% (even on the images that are already compressed by an image software such as Photoshop). When WebP is enabled on Themify settings, it will automatically generate a copy of the image to WebP format on the server. If the user's browser supports WebP, the generated WebP images will be used.
Themify Cache
The old Builder Cache has been replaced with the new Themify Cache system. The new cache system works on the whole site rather than just the Builder content. When someone views a page on your site, it will generate a static HTML file on our server. When the next person visits the same page, the static HTML file will be served. This can reduce the server resources and speed up page render because it bypasses the step to query the page from the database server and process the HTML source code.
