Synology 916+ slow file transfer from PC

mattyg · 10 Feb 2017 at 18:15

Hiya Folks

I'm trying to transfer my movie collection from my PC onto my NAS. But I'm getting painfully slow speeds. <10MB this is on a Gigabit network.

Nothing is obvious. But I can't check anything on the PC as it looks like my video card (8800GTX)has finally given up.

Are both devices negotiating @ 1000Mb/s?

mattyg · 10 Feb 2017 at 22:34

I can't check the PC as I cant get a picture. However the switch says 1000Mb/s

I have connections @100 and connections @1000 and my switch tells me what they are connected at so I think so.

How's your storage setup on the NAS?

In what way? I've set it up with SHR (raid5??) I've really just plug 'n play'd it. I've not had a massive play as I have a habit of messing things up like that. (If I don't KNOW what it does I try not to play)

Are you using the correct cables, CAT 5E or above? You could rule out the switch as being the cause by using a simple crossover cable to connect directly.

Using power line adaptors between your PC and the NAS?

You should be getting 110MB/s

edit.
Draw your network diagram in paint.. (with connection speeds)

I need to check back more often.

My NAS is sat on my server cabinet and goes straight into my POE switch. It did go straight into my Edgswitch but I swapped it whilst trying to find the answer

No powerlines etc. The rest of the house is networked through a patch panel into the 24port switch (not shown)

All Cables are either cat5e or cat6.

Orange is 10/100

List your switch models.

Many Poe switches are 100Mbit

Edit. Do you have 3x cables between the router and the switch...?

Yes 3 cables....Don't know why though.

24port switch is a
Ubiquiti ES-24-LITE EdgeSwitch 24-Port Layer 2 Managed Stackable Gigabit Switch w/ 2x SFP Ports

And the POE switch is a
Ubiquiti US-8-150W UniFi 8-Port Cloud Managed Gigabit PoE+ Switch w/ 2x SFP Ports

Anything that is supposed to be 100 is flickering orange and anything 1000 is flickering green??

Just use one cable between routers and switches.

It's possible to use more than one cable between switches, but you need to enable lacp on those ports.

For now just use one cable

I think the major issue is the PC I'm transferring too and from. It has 2 gigabit lan ports. But when I transfer direct from my laptop (wifi) to the nas I get 20MB/s but that is also the same when wired??. But that is better than the <10MB/s I was getting.

bledd · 22 Feb 2017 at 11:08

Just use 1x cable between devices unless you really know what you're doing with LACP configuration.

Where is your PC on this network drawing? -again, just use a single cable. Use a single cable from the NAS. (for now)

I knew I missed something.. It connected direct to the 24 port switch via 1 cable

The NAS only has two but they are assigned different IP's. Would that make a difference??

I've disconnected the 2nd (unused anyway)

As above, you only need 1 cable between the nas and switch, and between the router and switch.

Is the NAS being used for CCTV recording? If so then that will affect your transfer speeds (i.e. if trying to read from it whilst it is constantly recording)

Yes, only connect 1 cable. Once it's working well, you can look into teaming the ports and setting up LACP on both the NAS and the switch.

For now, make it as simple as possible. Your CCTV drawing with 4x cables, is that one box or 4x cameras?

X4 Cameras into the POE+switch. they are using a constant 2.5MB/s onto the NAS.

Would I benefit from connecting the NAS and the PC direct to that switch as its defo being underused (or disconnect the cctv temporally so its just the NAS and PC )

bledd · 22 Feb 2017 at 15:37

Worth doing a large file test with the NAS on the same switch (with the CCTV disconnected).
Note speed.

Connect up CCTV
Note speed.

Disconnect CCTV, move to other switch.
Note speed.

Connect CCTV.
Note speed

If it's just 2.5MB/s from the CCTV, then it shouldn't impact your normal copying speed much.

Armageus · 22 Feb 2017 at 15:37

yes if you can try without the CCTV recording to the NAS.

Although it might only be writing @ 2.5MB/s, if you are trying to read from it at the same time you are forcing the hard drive(s) to constantly seek to two different locations (which will cripple read speed)
