Maybe a bad question, but do you have an upload cap configured?

@ajroach42 not that i know of? i used the ubuntu snap install for which there is 0 documentation
@squirrel Right? so frustrating.
The upload cap would be the client, not the server.
I ran into that one when I was first setting up nextcloud.
@ajroach42 oooOHHHHHH RIGHT
dummy me forgot to check there
... yes, i did cap that and forget
do I feel like a dummy now
@squirrel 'Sokay, we've all done it at some point.
At least I know I have!
@ajroach42 hmm. still caps at ~4MB/s
wonder if there's a download cap on server now
@ajroach42 minecraft but no players atm...
... yikes yeah htop shows the cpu not having a good time
hrm.
@squirrel
What else is running on the server? (could be a RAM or a disk IO issue?)
