On the current version of Rancher OS (v0.7.1) I use a container that manipulate a lot of large files (4Gb or more) in a mounted volume.
All operations (copy, move, etc…) are exxxxxtremely slow (ex : 5 minutes to move a 4Gb file).
Here is an extract of my docker info result :
Server Version: 1.12.3 Storage Driver: overlay Backing Filesystem: extfs Logging Driver: json-file Cgroup Driver: cgroupfs Plugins: Volume: local
Any idea ?
