Enable a cache engine in WordPress or another web app
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 this 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 information on this subject.

Consumption of resources by a website is not necessarily linked to the number of your visitors. A well optimised, updated site with a correctly configured cache engine can withstand a daily number of visitors of several tens of thousands whereas a poorly optimised site can consume far too many resources with only a few visits per day.
