I have 2 unraid servers: one running 5.0b12a with 6 disks on the onboard SATA ports of aSupermicro X7SPA-F and my main server running 5.0 final with 16 disks on 2 M1015 controllers. When I do a readtest on different files with a Dune HD B1 mediaplayer I see average speeds of 8-9 MBytes/s on the 5.0b12a server but average speeds of max. 4 MBytes/s on the 5.0 final, which results in choppy playback of Bluray rips.

 

When I do the same tests over NFS I see speeds over 10 MBytes/s on both servers.

 

So my question is: Why is samba performing so badly on 5.0 final and can this be fixed?

All those speeds seem very low.  What type of network are you using?

All those speeds seem very low.  What type of network are you using?

 

It's a  Gigabit network but the Dune is 100 mbit. 10 Mbyte/s is 80 Mbit so close to the theoritical max of 100 Mbit/s.

 

Why is there a difference in speed between 5.0 final and 5.0beta12a? Is something else using samba?

Update:

 

I started the 5.0 final server in safe mode and streaming-speed over samba to my Dune has more than doubled.

 

What exactly does "safe mode" mean? I had the sabnzb, apcupsd. cache dirs and snap plugin installed. They are not running now.

Is virtually a stock go-file loaded?

 

What is the best and easiest way to mimic safe mode startup? A go file with only unmenu started, an empty packages folder and no plugins started?

 

Or can I create a backup of my usb stick, format and create a fresh 5.0 stable key + unmenu, copy the super.dat and license key and have my current install running again with correct disk assignment and array still intact? 

Safe Mode basically starts up unRAID with no plugins enabled.

See my sig.
