Speed Cache - Joomla Performance Optimization

Joomla have a native cache and Gzip compression system, that's a good start. Speed Cache comes over as a natural improvement of the Joomla page cache system with a lot of performance, compatibility and features enhancement.

To be more specific Speed Cache brings: a powerful static page caching, compatible with user sessions, a full browser cache system, a preloading cache system, a URL inclusion/exclusion cache control and a resource minification. Some handy tools are also part of the extension like the activation for logged in/logout users, an auto-index for caching URLs and an automatic cache cleaner on specified actions. Everything is under control from the Speed Cache dashboard.

Powerful Cache System and Browser Caching

cache-levels-joomla


Speed Cache for Joomla is coming over the Joomla default cache system with a new cache layer, by sending more static content (HTML) therefore reducing the number of database queries. Plus, you have the possibility to store the major part of the heavy page resources (like images) in the browser cache. And you can clean it when you want!

 

Speed & Cache Where you Want

URL-cache-inclusion-exclusion

The Speed Cache cache is activated on a selection of pages of your website, the system is very flexible and you're always sure that it works on every website. You can also do a batch import of URL from a menu to the cache system. The cache inclusion/exclusion system is very powerful:

  • Include single URLs
  • Exclude single URLs
  • Include from cache a set of URLs based on rules (regular expressions included)
  • Exclude from cache a set of URLs based on rules (regular expressions included)
  • Per URL define: Activate cache for public and/or for registered users
  • Per URL define: Preload cache URLs for public and/or registered users
  • Per URL activate the cache preloading per user 

 

Dynamic Elements in Cache

speed-cache-loggedin

 

The main problem with serving static content, like the Joomla Page cache plugin, is that it does not work at all with dynamic elements and user sessions. Speed cache got 2 systems to avoid the problem of cache on dynamic content:

  • Speed Cache generates static cache file per Joomla user then it also works for dynamic content (like form, sessions..)
  • Not sure about it? no problem, there's an option for each page URL to include/exclude logged in users from the cache
  • You can also preload cache per user right after a clean cache

 

Clean all Cache and Regenerate it

clean-generate-cache


Speed cache can get rid of the cache cleaning problem, all caches (Joomla, Speed Cache static and browser cache) can be cleaned in one clic or automatically based on action. Indeed, on backend/frontend actions like save a content, all cache can be cleaned. You can also regenerate automatically all caches, so no one will wait for the cache generation anymore.

Resources Minification

minification-file-cache
