“Fast Backend” will only have affects to the Admin area of WordPress and won’t have any impact on your theme.
Native Lazy Loading of Images
The plugin adds loading=”lazy” attributes to images if missing to take advantage of native lazy loading.
Reduced WordPress Heartbeat
Usually the WordPress heartbeat is every 15 seconds. The plugin extends the time period to 45 seconds.
Autosaving every 2 minutes
Instead of autosaving posts every 60 seconds, we’ll do this only every 120 seconds.
Loading of plugin stylesheets in the footer
The plugin moves plugin stylesheets to the bottom of the page to prevent them to block rendering.
