Setting up a cache engine on a CMS/Optimizing a website
When we detect that your site consumes more resources than the other sites on the same server, we analyze the case and often we find that a simple change of an application or parameter will optimize your site and the server as a whole. You will then be contacted by email about it and we wil 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

Log into the administration of your Joomla CMS, then go to:

- 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 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 optimized, updated and configured correctly with a cache engine can handle a daily attendance of tens of thousands of visitors, while a poorly optimized site can consume a lot of resources with just a few hits a day.
Optimizing a website is essential for a site with a somewhat consistent attendance. If necessary, even a dedicated server is no longer sufficient over time.
