Hi Max,
Even if you don’t have performance issues, caching helps drastically reduce the load on the server so if your site gets any traffic at all it would definitely be a good idea to setup caching to reduce server strain, prevent possible server throttling and of course speed up loading times. It’s also possible your server already has proper caching setup, most good WP hosting solutions have built-in cache so there is no need for a caching plugin.
If that plugin you mentioned already has the function you need, why are you considering switching to this one? Just curious.
It’s possible the plugin is passing the end/start dates to a javascript file and then using that to hide the message, which would bypass any caching concerns. But this does bloat up the plugin functionality.
I made this plugin to be slim and fast so I’m just hesitant to add more code/bloat unless I get significant requests for the feature. For example when I first released the plugin it didn’t have a “dismiss” functionality and that’s something I ended up adding because of the incredible amount of requests for it.
Hope you are having a nice weekend and not working too hard like me ??
