Change delay in preloading cache

FlyingPress default adds a delay of 0.5s while preloading the cache between each page. This slows down the process and ensures your server doesn't run out of resources.

Here is how to set to delay as 1s - recommended for very low-resource servers:

add_filter('flying_press_preload_delay', function(){
   return 1;
});

If you have a dedicated or high-end server, you can remove this delay by setting it to 0s as below:

add_filter('flying_press_preload_delay', function(){
   return 0;
});
