If your website is slow to display, the visitor will go elsewhere. Hence the importance of the loading speed of a website
The loading speed of web pages has always been a point that Google put forward.

Display speed and user experience intimately linked
Any organization in charge of a website (company, institution, association, …) must be aware of the importance of the loading speed of its various Web pages. The speed of a site strongly impacts the user experience well before arriving on the site. It is also the first UX element of a user, giving him his first impression, well before seeing any visual site or experiencing a navigation that would not necessarily be very ergonomic.
The impact of speed influences many criteria, which can become a force for a website with good performance or, on the contrary, be a real obstacle to the achievement of its objectives.
