Adrian, can you provide more details on the performance issue you're seeing?
We do have some scripts to collect data to analyse. Perhaps you can run
this and provide us the details in a bug. The ansible scripts to do this is
still under review -
https://github.com/gluster/gluster-ansible-maintenance/pull/4
But would be great if you can provide us some feedback on this as well.
