Gluster users - Jun 2019 - very poor performance on Debian Buster

I run glusterfs server on a sys-V version of Debian Gluster. The
machine is an 8-core/256GB/SSD server and I want to copy 400GB to a
mounted gluster device. The copy now runs for more than a day and it
has only copied 79GB. The network activity is around 4 to 8 Mbit.

Is this a known issue of version 5.5-3? I did not touch the defaults.

R.
