Hello!
After fiddling around with F...Nas for some time i stumbled over OMV .... great, exactly what i was looking for. Thanks a lot to Volker for this great project!
But unfortunately i encountered some performance issues.
Configuration:
TEST MACHINE:
Apple MBP Retina, last gen, SSD, connected with Thunderbolt Ethernet Adapter to Gigabit Switch
F...NAS:
HP N54 Microserver, 16GB Ram, USB Boot, 4x3TB HDD with ZFS, F...NAS 9.2.1.7
OMV:
HP N54 Microserver, 4GB Ram, SSD Boot, 4x2TB HDD Raid5/XFS, OMV 5.x and OMV 1.x (tested both, latest versions)
---
Raw Network performance:
Both are equal.
From the Mac to the Machines i get 945MBit/s TCP and 1.05Mbit/s UDP Performance with iperf 2.0.5, so they seem ok (i know there were some problems with the onboard NIC from broadcom in these machines, but read on)
---
SCP:
Here OMV is faster (tested only with OMV 5.x).
2.8 GB iso file copied from Mac
OMV (to SSD root drive and to RAID):
100% 2821MB 65.6MB/s 00:43 (SSD)
100% 2821MB 70.5MB/s 00:40 (RAID)
(same file copied local with the shell from SSD to Raid: 12.5sec and from Raid to SSD: 27sec ... so the storage seems not to be the bottleneck)
F...NAS (to ZFS Raid):
100% 2821MB 45.5MB/s 01:02
---
SMB:
Here i tested with two Tools. XBench and Blackmagic Disk Speed Test.
Doesnt look so good for OMV

Its not that much, but it gets worse:
Blackmagic Disc Speed Test (simulates reading and writing of files for video editing), 5GB stress test:
F...Nas:Write 107MB/s, Read 103.5MB/s
OMV Kralizec:Write 60MB/s, Read 61MB/s
OMV 5.x:Cant remember exactly, but it was worse ... write between 60 and 15MB/s !!!
So my question: Why oh Why???
