Extend kit cache time
However, many of our customers don't change their kits for long periods of time and would like to be able to extend the cache time to improve the site's performance. It is common to edit a kit often while designing a site, but not make any changes to the kit once the site is live.
To support these cases, use the “optimize performance“ setting under “Kit Settings” in the kit editor.
After ticking the checkbox, you’ll need to click “Save Settings” and then republish your kit for the changes to take effect.
A word of caution: updating optimized kits Increasing the cache timeout means that you will no longer be able to make quick changes to this kit. When this option is enabled, updates may take up to a week to be visible to all your visitors; disabling the option won’t take full effect until after a week, either. Use this option only if you don't plan to make any further changes to your kit.
