There's something very wrong in your Docker storage setup. You need to
be using aufs or btrfs. Some filesystem that does overlays or snapshots.
60s sounds like it's doing file copies.

We do a lot of Docker where I work and starting a docker container
that's already downloaded is *instant*. No noticeable delay at all.
