Setting up a cache engine on a CMS/Optimising a website
When we detect that your site is consuming more resources than the other sites on the same server, we analyse the case and often we find that a simple change of a request or setting will optimise your site and the server as a whole. You will then be contacted by email about it and we will explain the steps to take in order to correct the problem.
In this email, we will ask you to install a cache engine and this guide provides additional guidance on the subject.

Joomla 3.x: configuring the cache
Log into the administration of your Joomla CMS, then go to:
- Setup Menu -> System tab -> Cache Settings
- select conservative or progressive Cache (Joomla developers recommend the progressive cache, but you should test the effectiveness of both modes)
- Select the maximum validity time, in minutes, for a cache file before it is refreshed. 60 minutes if your site is changed regularly. 20000 for a static site which changes only once or twice per month...
- Save and purge the cache manually via the System menu if needed

The consumption of resources by a website is not necessarily related to the number of your visitors. A site that is properly optimised, updated and with a correctly configured cache engine can handle a daily attendance of tens of thousands of visitors, while a poorly optimised site can consume a lot of resources with just a few hits a day.
Optimising a website is essential for a site with a barely consistent attendance. Where relevant, even a dedicated server is no longer sufficient over time.
