Hello everyone, I installed Nextcloud on a Proxmox VM using Ubuntu 22.04, running Docker, using the AIO. The VM has 4 cores and 8GB RAM, the only things running on this VM are Docker, Nextcloud and the Cloudflare Tunnel. I feel the interface is a bit sluggish and it stutters some, the CPU is under 2% usage and it’s using about 6GB out of the 8GB RAM, so I’m not sure what the issue could be, should I bump the RAM some more? Or are there other configurations I should be looking at? Any help is appreciated! Thank you!
