Hello,

I just finished setting up my first unRaid server. I've got all my plugins and dockers setup and running perfectly (Plex, Sonarr, Radarr, NZBget). Everything seems fine except when I tried to move files from my Win10 machine to the shares. My read and write speeds hover around 3mb/s which is insanely slow. Here's my setup:

 

Model: AMD X2 250

M/B: Gigabyte Technology Co., Ltd. - GA-890GPA-UD3H

CPU: AMD Athlon™ II X2 250 @ 3000

HVM: Enabled

IOMMU: Disabled

Cache: 128 kB, 1024 kB

Memory: 4 GB (max. installable capacity 16 GB)

Network: bond0: fault-tolerance (active-backup), mtu 1500 
 eth0: 1000 Mb/s, full duplex, mtu 1500

 

I have 3x WD RED drives (3TB), with one as parity, and no cache. Running hdparm yields the following:

 

root@Tower:~# hdparm -tT /dev/sdh

/dev/sdh:
 Timing cached reads:   4788 MB in  2.00 seconds = 2394.06 MB/sec
 Timing buffered disk reads: 416 MB in  3.01 seconds = 138.17 MB/sec
root@Tower:~# hdparm -tT /dev/sdg

/dev/sdg:
 Timing cached reads:   4802 MB in  2.00 seconds = 2401.77 MB/sec
 Timing buffered disk reads: 466 MB in  3.00 seconds = 155.19 MB/sec
root@Tower:~# hdparm -tT /dev/sdf

/dev/sdf:
 Timing cached reads:   4698 MB in  2.00 seconds = 2349.51 MB/sec
 Timing buffered disk reads: 444 MB in  3.00 seconds = 147.77 MB/sec
 

So it seems that the transfer speeds internally are fine but I'm having major problems over the network. I'm using an Archer C7 and my PC and the unRaid server are hardwired.

 

Any suggestions? Thanks.

Post up your diagnostics file.  'Tools'   >>>  'Diagnostics'.  Upload that file with your next post.  

 

Questions: 

Is both uploading and downloading an issue?  (It is not completely clear in your first post.)

Do you have another  computer to check the speeds with?  (Even a set-top media player that plays video would be a substitute for a computer.)    

Do you have the latest NIC drivers (from either the PC manufacturer or MB manufacturer) installed on the Win10 computer?

Check the error rate in the GUI when you copy.
Could be the onboard NIC on the unRAID machine. Probably a realtek chip!?
How is streaming with Plex? No stuttering?

Both upload and downloading is problematic. ~3Mb/s

I tried accessing the shares from a laptop connected wirelessly and the speeds are a bit better, 12Mb/s read and 8MB/s write

I also tried accessing a share on my Win10 machine for the laptop (no Unraid invloved) and the speeds are also ~3MB/s

Latest drivers are installed (Intel NIC on my machine, Realtek on server).

Plex streams fine so far, but I'm only running one stream at time (SD/720p max).

 

Attached is diagnostics file.

 

I'm starting to think that the Win10 machine is the culprit. I'm connected through a powerline adapter but it never caused issues in the past.

From your last post, I would gather that you are running a real mixed bag of devices and protocols on your network.  It would be best for testing purposes to use all wired ethernet with no wireless or powerline adapters.  Let's be working on one problem at a time.    (Some folks have had great luck using powerline adapters and others have had real problems.  Through-put on Wireless can also be a mixed bag depending on your location (I can see about 15 wireless routers where I am) and  this can increase interference.  And the primary wireless frequencies is also 'shared' with a lot of other services including microwave ovens which can effect through-put.)

 

You unRAID NIC is running at 1Gb so that is good and I didn't see any indication in the syslog that the NIC was having any problems.  If your not seeing any errors on the Dashboard (under "System Status" --errors), I would assume that the problem is not in the server NIC part. 

 

You seem to have some dockers running and apparently one of them is PLEX.  You said the CPU was an " AMD X2 250 " and that has a CPU passmark of ~2000 which is a low end processor today.  I would suggest for testing purposes to shutdown the Dockers and see if things improve. 

 

(There also appears to be some errors in the syslog regarding some of these Dockers.  I would suggest that you have a look to see if the settings are all correct for what you are trying to do.  You might have to ask for help in the support threads.)   

Thanks for the help Frank. It seems that my PC might be the bottleneck here, not unRaid. My powerline connection is 100mbps so I might not be able to reach anywhere near maximum write speeds. Although I would still expect my shares to be around 10-12 Mbps atleast. I'm considering picking up an AC wifi adapt and see if that improves things as a direct hardwire connection to the router is not possible at the moment. I'll also try stopping the dockers and checking the speeds to see if there's any improvements.

Be a bit careful about data rates.  Normally, Windows Explorer reports transfer speeds in MB/s--- That's megabytes per second.  But you network speeds are measured in Mb/s--- That's megabits per second.  There are eight bits per byte plus some bytes for network overhead and housekeeping.  So your Explorer speeds of 3MB/s is approximately 24Mb/s as network speeds are  measured.
