I recently rebuilt my home server using containers instead of (qemu/KVM) VMs and I notice a performance benefit in some areas. Although I just use systemd-nspawn containers rather than docker as I don't really see the need to install 3rd party software for a feature already installed on my OS.
I handle snapshots by using btrfs. Works great
Anybody used this yet? Will this be the btrfs killer I've been hearing it might be?
