Apologies I was away on business.

My read performance is well below yours!

hmm

 

your nas is configured as Raid6 with 9 disks - if a quick read of this thread is correct?

 

So the slow read values would explain why your emby scans are slow!

 

Those read speeds are about or less than a single disk

 

Ah just spotted your array is almost full with only 7% free - that would account for some of the issue as 10% or more is needed not to see a slowdown on QNAP Raid

 

Your write is a little low but thats probably because you are using WD Red rather than Red Pro/HGST 7200 rpm drives

Correct - Disk 10 will be added soon.

 

I can't understand why they are so slow tbh.

 

Ill clear up some space on the NAS above 10% or order another drive to see if it helps.

 

I can saturate the NAS by uploading from 4 PCs a get write speeds much higher than what the NAS is quoting.

[PenkethBoy 2063]

full disks are always slow as you are reading from the slowest part of the disks (centre) rather than the outside which is usually the quoted speed for a disk

 

Also when Emby is reading its doing so from random locations not sequential which always kills any read speed - unless its an ssd which can cope better with random reads

 

some of the apparent faster write is due to caching in nas memory as you have 32 gig - i suspect if you upload from 4 clients with large (say 40 GB+ each) files at the same time you will see a significant slowdown

 

are you using port trunking for your clients i.e LACP?

 

[edit]

 

if you dont believe the Qnap DT then install "NetData"  https://forum.qnap.com/viewtopic.php?f=320&t=121518&hilit=netdata

 

1.9 is the latest version
