Cache Settings in AllEvents

What is a Cache?

A cache is a method of storing previously retrieved information for a certain amount of time temporarily. For AllEvents, when the first user requests a Joomla page with a AllEvents (or plugin) on it, the data is retrieved from the database or calendar source. This takes time. Time to retrieve and process the information. When a second user requests the same page and the cache is enabled, the information is pulled from the cache (memory) instead of the original source. This is faster and uses less server resources. However, the information will be minutes old. For most users the delay is not noticed. If you are responsible to update the calendar, you might not see the update for several minutes after you made the change. This may upset some users that want to see their changes immediately. Turning off the cache will show changes more quickly but can slow your site down considerably.

Joomla has a caching system as does AllEvents and other extensions, they will be explained more deeply in the next chapters.

Global Joomla Cache

The best cache option for your site is the cache plugin, which caches the whole page. Means that no PHP code is executed at all, will relax your server and deliver the pages faster.
