Dear Community,
I'm quite puzzled with this situation.
1. Added 'server.allow-insecure on' (with 'option rpc-auth-allow-insecure on' in glusterd.vol)
Volume info after that change:
Volume Name: data
Type: Replicate
Volume ID: 9b06a1e9-8102-4cd7-bc56-84960a1efaa2
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: ovirt1.localdomain:/gluster_bricks/data/data
Brick2: ovirt2.localdomain:/gluster_bricks/data/data
Brick3: ovirt3.localdomain:/gluster_bricks/data/data (arbiter)
Options Reconfigured:
performance.client-io-threads: off
nfs.disable: on
transport.address-family: inet
performance.quick-read: off
performance.read-ahead: off
performance.io-cache: off
performance.low-prio-threads: 32
network.remote-dio: off
cluster.eager-lock: enable
cluster.quorum-type: auto
cluster.server-quorum-type: server
cluster.data-self-heal-algorithm: full
cluster.locking-scheme: granular
cluster.shd-max-threads: 8
cluster.shd-wait-qlength: 10000
features.shard: on
user.cifs: off
storage.owner-uid: 36
storage.owner-gid: 36
network.ping-timeout: 30
performance.strict-o-direct: on
cluster.granular-entry-heal: enable
server.allow-insecure: on
Seems no positive or negative effect so far.
2. Tested with tmpfs on all bricks -> ovirt1 mounted gluster volume -> max 60MB/s (bs=1M without 'oflag=direct')

This indicates to me that it's not a problem in Disk/LVM/FileSystem layout.
Most probably I haven't created the volume properly or some option/feature is disabled ?!?
Network shows OK for a gigabit:

I would appreciate any hint how to proceed further from this point!
Thank in advance.
