Thank you for your review.
However – there is no way to make it faster. You should check if your hosting provider has any issues or if can get better hosting. Often slow databases or outdated PHP versions (older than PHP 7) cause slow page loading times. Sometimes shared hosting is quite slow since many other websites run on the same server.
For comparison – my demo website for Timed Content usually loads within 1-2 seconds, depending on the internet connection speed:

But also on other websites where I use my plugin there is no slow down by the plugin.
