Run through NextcloudPi within Docker on a Raspi 4B - 4GB with extensive cooling and a great power supply.
The issue you are facing:
Everything is so slow.
Everything is so slow since minute 1. I spent the past week tweaking my installation to my needs and now I have come to optimize the installation, just to find out it already was optimized by default. I tried searching different methods of optimization, but all I found was already applied.
At first, I had the entire installation on my Transcend 300S SD card (very high quality) and it was slow. Now I moved the Nextcloud data directory to an HDD. Still slow. No matter what I added/removed/changed with Nextcloud, everything is super slow.
I think the fastest load time I encountered was 10 seconds. Everything else is above that. Sometimes way above that. A couple of times it even took about ~60 seconds to load the Nextcloud page.
I am generally very patient and deal with longer load times with ease but Nextcloud just takes a super long time, that sometimes is unbearable, especially if you quickly just want to drop in something you need.
I have read some older articles on how to optimize Nextcloud. Some suggestions weren’t compatible with my installation, others were already applied. I did not find an up-to-date article, though.
As I use a Raspberry Pi 4B with 4GB RAM available, I have plenty of power to use, I just don’t know how I let Nextcloud use it better.
As this is a new instance, there are so far only 2 users of it.
What can I do to make things faster?
What hardware component has the biggest impact on performance? (Storage, RAM, CPU, etc.)
FAQ:
Q: What feature of Nextcloud causes long load times?
A: Any feature.
Q: What about the hardware XY part?
A: The hardware is perfectly fine and is rigorously tested to work as expected.
Q: Did you install a lot of apps?
A: Apps or a bigger installation don’t have anything to do with that, as it has always been slow since the beginning.
Q: Did you play around with the config or with the database?
A: It is slow since minute 1, before I did anything with the instance after installation.
Is this the first time you’ve seen this error? (Y/N):
No. I installed Nextcloud about 1 year ago already and it was super slow as well. On entirely different hardware, in an entirely different location.

Logs are bloated with stuff that happened when I tried optimizing the instance. Nothing else of intereset to see.
