[Gluster-users] gluster write performance

Looked a lot from forums, but didn't find much..
So I've got glusterfs 3.6.4
1 Gbps network
replicate and distributed volumes

so when i read from any of them, I get maxed-out network performance
(around 80-120 MB/sec)
If i write to distributed volume, I get 16 MB/sec
If i write to replicated volume, I get around half of it (which is logical)

i use XFS (with all set recommended options) and EXT4 for gluster. no
Disks are in HW RAID5 for Distributed volume and RAID0 for Replicated volume

volume options:

performance.write-behind: off
server.allow-insecure: on
cluster.server-quorum-type: server
cluster.quorum-type: auto
network.remote-dio: enable
cluster.eager-lock: enable
performance.stat-prefetch: off
performance.io-cache: off
performance.read-ahead: off
performance.quick-read: off

Am I missing something?

Best regards,
