Read Test avg speed on 1Gbps LAN

[HouseOfMu]

Hi,

Dune Vision 4K

In an effort to improve playback of large high bitrate 4K video files, so I bought Asustor NAS and doing the Dune Read Test I have seen a slight increase in the Read Test Average Speed compared to my microserver, but it still on occasion (3/4 times in a film) stutters.

Tests on various large (50GB+ 4K dolby vision files):

From Microserver (windows 10).  SATA II (300Gb/s) 5400rpm drive - Avg read speed for SMB: 70 - 90MBs

From Asustor NAS. SATA III (600Gb/s) 7200rpm drive - Avg read speed for SMB/NFS: 90 - 130MBs

I was expecting much more of an improvement, possibly in  the 200MB/s region due to SATA-600, but thats not the case.

The Dune is connected on a 1Gbps ethernet LAN to both boxes (a switch), so makes read testing easy once the sources are setup.
I've tried using both SMB and NFS, which is marginally better most of the time (~ 10MBs) over SMB.

The Asustor does have a 2.5Gbps LAN port but I'd need to update a couple of switches to be compatible to take advantage, even then I'm not convinced the LAN of 1Gbps is imposing any form of limit on the throughput, and of course the Dune only has a 1Gbps port (might be able to use 2.5Gbps USB adapter though?).

Anyway, LAN upgrade possibilities aside, how do these figures compare to anyone else who also plays files their LAN ?

I'd appreciate some comparison figures.
Thanks

Having posted that , I've found some enlightening information on avg/max LAN throughput figures in thsi article.
https://www.online-tech-tips.com/computer-tips/understanding-lan-network-transfer-speeds/

If you have a gigabit ethernet card on your computer, your router or switch is gigabit and the receiving device also has a gigabit ethernet card, your max transfer speed jumps to a much better 1000 Mbps or 125 MBps (125 megabytes per second).

Again, you won’t get that theoretical speed, but you should be getting anywhere from 70 to 115 MBps depending on the type of files you are transferring and your network setup.

most hard drives (SATA 3.0 GB/s) will max out at a read speed of 75 MB/s

His figures seem slightly lower than I'm getting for a SATA III HDD, but maybe 1Gbps LAN is more of a limitation than I thought?

You won't see 200MB/s due to the 1Gbps ethernet port on the DUNE.

You could get one of these to check if it is compatible with the DUNE:

however my question would be why do you need that speed? Even 70GB direct rips from 4K Blu-ray are way less than 1Gbps. An example a 2 hour film at 70GB = 9.72MB/s!

I get read speeds between 80 - 120MB/s for NFS shares, SMB a little slower.

I get no stutter on even the higest bitrate files.

EDIT: Example below playing one of my highest bit rate files:



11MB/s

if your able to read from your nas at 90-130 then there is something else going on causing your stuttering as car said most UHD 4K 1:1 rips max out at around 85 mbs or 11 MBs then with atmos your looking at 12 ish MBs max

are you running an UpToDate FW or try a reflash with the new GUI beat fw

Hi, thanks for your replies.

So my Read Speed figures do seem to be consistent with others and inline with 1Gbps LAN throughput, which as you say, should be more than enough for even the highest bitrate UHD.
I tried playing from USB and no issues which means the LAN throughput must be dropping at some point.

Do I have to downgrade the f/w version in order to re-apply a later one ?
thanks

Nope.

Later versions have no problem with LAN speed.
