How to speed up nextcloud on raspberry pi 4?

Question

ubuntu

Installed nextcloud. So far, everything is spinning like this: there is an 8GB microSD card and a 64GB USB3.0 flash drive. The speed of work is very sad. The main page in the browser opens for 10-20 seconds, thumbnails and photos are loaded even more. I sin on a memory card, but there is no other yet. The whole system takes up 600MB of RAM. I have the 4 GB version. Is it possible somehow to unload the whole system into the RAM and at the end of the work so that it writes the changes to the memory card?
Now I mounted tmp into the RAM, but it didn’t give much growth

Answer 1

Not the most suitable hardware for such software. Are there any serious reasons not to deploy it, for example, on the most simple VPS with a normal processor and disk?
