Deferring Block Loading
Speeding up page loads by specifically targeting blocks containing slow-loading content.
Deferred block loading renders the content of a block after initial page display, which can improve page load times.
Defer rendering a block until after the initial page load:
Check the Defer Loading option Theme Press Control Panel > Page Tab > Block > Handling
Not all block content can be deferred successfully.
Because some macros rely on page initialization, functionality should be tested after enabling the Defer Loading option.
Use deferred block loading to render a specific block every time a page is viewed, regardless of the Instant Page Cache setting.
