 * I use WP-Optimize for caching and have the “cache-issue”, so I have to use the
   Ajax-option to prevent that Event-IDs are cached. This use of admin-ajax.php 
   slows down my site for 1.3 sec. Can you tell me what script I can exluce from
   caching to leave the Ajax-option unchecked? Thank you.

 * Or maybe you know a caching plugin witch is working without the cache-issue?

 * I am interested too. It seems like there is a consistent load on the server when
   API and AJAX is checked. When 40-50 on site, the load on server is not negligible.
   
   Using a 6 core 8GB ram Litespeed VPS only with one site on it.
 * How we can optimise this?
