Use networks Content delivery
If your website displays a lot of data, it's best to use the Content Delivery Network or CDN. The network can use strategic servers in different situations, in which case content will be displayed to visitors in a shorter time period. The CDN server can load content faster in the system and speed up the website.

The free and best(in free) CDN, I would suggest you Cloudflare. I personally use Cloudflare to speed up my website by rocket loader, Brottli, Minify, and few other cache mechanisms. Not a lot but at some extent, the speed can be boosted.
