In WordPress, Joomla, Magento and other CMS, sometime happens that the website can load very slowly or at low speed.
The first thing we advise is to do the following TEST to evaluate the optimization of your website code:
It is important that both scores (mobile and desktop) are green because the badly programmed code (sometimes just a comma in the wrong place) or an outdated or low quality plugin, can make all the processing of the web slower or at low speed
Activate Cloudflare from your cPanel to perform a more thorough search of your website on different servers and load faster.
Install caching plugins WordPress, Joomla, Magento, etc.
