Mine is nice and quick in regards to the web interface and general functions. However I run it on a server at home and my upload speed isn’t the best, so if I need to pull a larger file (Files On Demand enabled) then obviously the transfer speed of the file is a bit sluggish.
Hosted on a VM with 16GB RAM, 4 cores. Using the NextcloudAIO docker deployment option, all behind an Apache reverse proxy (I have a bunch of other services on another VM that all have reverse proxy access in place as well).
Nothing too special, just had to do some fiddling to get the Apache reverse proxy working correctly. Now I believe they have a pre-made example for it, but back then they only had nginx. I stick with Apache because that’s still what I know. Might start learning nginx, but my main work isn’t in web stuff.
