Hello Derek,
We have a 10Gig connection dedicated to the storage network, nothing else is on that switch.

Hi,
Another question which I don't see answered: What is the underlying connectivity between the Gluster hosts?

Hello Sunil,
[root@ovirt1 ~]# gluster --version glusterfs 8.6
same on all hosts
Latest Release-10.1( https://lists.gluster.org/pipermail/gluster-users/2022-February/039761.html) has some performance fixes which should help in this situation compared to the older gluster bits.
