Import music from NAS to Core, speed very slow, just around 10MB in giga network

Posted by: marcobb on 31 October 2017

As topic, is it normal ?

Thanks !!!

That’s the speed I get when copying files from the computer to the Nas over the network.

This could depend on if Naim we’d tight on the mic with the core, is it gigabit?

The Core is Gigabit, as is the Unitiserve. I haven't found my US to be particularly slow at transferring data either way, although I've never measured it.

Its nothing to do with the network,  or whatever gig or not the Core is,   It’s the processors at ether end.  10MB is normal

I am using synology 1813+, I don't think it was the hardware performance issue. I found the speed can up to 40MB while transfer the file from Core to PC/NAS but PC/NAS transfer to Core is 9-10MB only, don't know what is the Core problem.

Same here, around 10 max, mostly around 9 for larger transfers. 

Having to transfer some 400 GB from one NAS to another I found it much faster to use a 128 GB USB 3 stick. I set up the NAS to automatically backup parts of the music folder when putting in a USB stick. The other NAS I set up to automatically copy from USB stick to the music share. Takes a little more effort than simply copying from one drive to another, but with 30-50 MB/s it's faster when you have to copy a large amount of data.

Cheers Mike. I have sometimes wondered whether the 10MB I always get was slow or not. It seems it’s not. Hurrah.

That's a bit misleading; unless the files are being modified between read and write then the storage devices and interface bus handles the file transfer. Speed is limited by bus and device transfer rates not CPU.

Core is slow at file handling -- try importing from a fast SSD USB external drive, and you will see what i mean

Really ??? But my music all in the NAS, it is 2.6TB.

I’ll leave to you guys to aurgue this one,  I have travellling to do,  as I said before it depends what you have at each end, some ends are faster than others & the slow end is the pacemaker.  And to go back to the original question,  a giga network won’t make it any faster.

If your music is a nas, why would you be importing the files into your core?

Posted on: 01 November 2017 by DiscoVolante

Presumably because the Naim import process adds metadata to be compatible with the Naim app?

Certainly a beefier machine at each end is going to help. I bang on about these low power nases, but apparently I am wrong.

because I tested the music store in core have best SQ.

Whatever actually is the bottleneck, I doubt the seemingly slow 10MB/s is anything negative to do with the Core. Having just copied a single 220MB flack file from my windows laptop (new machine, Win 10' ssd) across my gigabyte network to my Mac Mini (ssd), the rate was just 3.7MB/s, with nothing else running on either computer or network. (NOte to self - why is mine not achieving 10?)

It will be a number of factors, but in your case its almost certainly not the machines, I copy between macs and PCs all the time.

Are you certain its a gigabit network, any switches in the mix? 

I don't believe routers would have much to say in this scenario, its done its duty of assigning the IP addys, but if your router is also your switch, is it any good?

A likely culprit would be antivirus software scanning each file as it's transferred.

Looked into a bit further, and have learnt something: 

I had connected cable to the laptop, going via a gigabyte switch centrally in the house to the Mac. However I hadn't switched off the laptop's wifi connection (its routine connection), which goes to wireless access point, and through cable from that to the aforementioned switch and so to the Mac. I've just tried the same file transfer with the laptop wifi switched off - and it went at ~100MB/s, so at about 800megabits/s not far off the gigibit network rating, of course ibcluding the read/write actions. (N.B. in my first post I was careless and called the network gigabyte, when of course it is gigibit.)

what I hadn't realised was that although after plugging in the network cable the laptop displayed that it was connected by cable not wifi, the data transfer apparently remained locked to wifi and ignored the cable - I had always assumed it would use the fastest connection. So i now know I need to switch off the laptop's wifi to benefit.

The slow speed just appear in import/written data to Core only, otherwise is no problem.

On a mac you got network in prefs in here you can drag the networks about, this will give a default depending on how high up in the chain it is.

Not so sure in pc, there must be a way to set priority, I'll take a look.

100MB/s sounds better.

I have ac wireless so see around 70MB/s there. AC is shweet!

Over 72 hours, just finish 50% only (Total files size is 2.6TB), It is not reasonable in today's computer generation 

My friend ask me if he has 11TB data, then need use one month to import
