I have a gigabit interface on my workstations and sadly I have no option for upgrade without switching the hardware. 
I have observed my network traffic for days with iftop and gtop and I have never reached my Gbit interface's maximum bandwidth, not even the half of it.
Even when reseting my bricks (gluster volume reset-brick) and running a full heal - I do not observe more than 50GiB/s utilization. I am not sure if FUSE is using network for accessing the local brick - but I  hope that it is not true.
Checking disk performance - everything is in the expected ranges.
I suspect that the Gluster v5 enhancements are increasing both network and IOPS requirements and my setup was not dealing with it properly.

>It's definitively planned, see: https://bugzilla.redhat.com/1693998>I'm not really sure about its time plan.
I will try to get involved and provide feedback both to oVirt and Gluster dev teams.
