Caching
For really big maps, caching is a must. While we don’t really recommend using Mapster WP Maps for maps that have more than 10,000 features on the map at once, it can definitely be done. But it’s important to cache the map, so that your database isn’t trying to fetch and sort all those features every time someone lands on the homepage.
Your WordPress installation or a service like Cloudflare might already cache API responses, but Mapster Pro comes with a caching feature you can use directly that’s very efficient.
You can use this to generate a static file with all the features that will load on your map. Then, whenever you make a change or add more features, you just need to regenerate this file manually, and your map will load many times faster than it would otherwise.
