As the title says I have noticed the considerable performance difference that exists in Flarum with respect to desktop and mobile. I do not know if it is a known problem and if it is something that is already taken into account for future versions of Flarum. Here is the comparison of results in PageSpeed Insights.
Desktop:

Mobile:

Can you share your results, I would like to know if some of you also have problems and if you have managed to solve them in some way ... both with Flarum and with server settings? Memcached or Redis Cache could help?
