Performance issues on docker swarm

[kale1d0code]

I'm having difficulties authenticating in a timely manner using the atmoz sftp service.

on average it takes 5 to 10 minutes to authenticate and the service consumes most resources on the server during authentication.

We are using:
The alpine variant of the image
an encrypted password for our user
UID and GID for the user is set to 1.
The volume mounted in the container is in use by 1 other container however I doubt sharing the volume is the cause as sftp works normally after authentication and we've never had problems with file access conflicts.

I've solved this using the docker swarm equivalent of the settings found in this issue: #405
