I’m using a AMD Ryzen 7 3700X with 64GB of RAM for my main server. Looking at it right now (so just light background activity) the services are using ~3% of my CPU and 10GB of memory. Granted my ZFS cache is using 32GB of memory, I could tune that to use less, but I have enough headroom to make that fine

I opted to just use the Bitwarden service to avoid depending on my services to get my secrets for my services, so I haven’t tried running it, but I have heard good things about Vaultwarden. I’ll eventually try running that as a backup
