DS212j performance problem [merged thread]

[almondos]

Are you transferring data from your PC to the Synology or from another device on your LAN ??

So far my PC. Eventually I plan to link up my smartphones and my tablet. But right now I've used my desktop (farthest distance away), my netbook, and a laptop. It's become pretty obvious that distance plays a major role as the desktop gets the worst transfer rate. But, is being ten feet away and getting 1.5 MB/s considered decent?

I am getting similar speeds (approx. 1.5 MB/s) and I was also very suprised at how slow the transfer was. Is there something we are doing wrong? I was expecting it to be much faster. Unfortunately because of the layout of my flat I cannot plug in directly.

I'm also facing super slow transfer speeds. My NAS is connected to a WRT310N Gigabit router and my laptop is connected wirelessly. So I'm trying to transfer all my pictures from my laptop to my NAS via wireless connection and I get max 2 mbps speeds, Awful. Does anyone know how to improve transfer speeds?

Sure ; use a cable ... wireless is fine for surfing the net and e-mailing, but for data transfer you need a wired connection.

well i can report the same problems. i have very slow transfer rates (~2-4 mb/s) with my ds212j. i'm using a d-link dir 655 router but didn't expect any problems, because of granted capability from synlogy. i'm also using my diskstation via wlan, too, because in my opinion it's useless to put always a cable on, while transfering data between my diskstation and my notebook. there are even lags while hearing music or watching videos via wlan.
i have to mention that i have normal transfer rates while conecting my diskstation directly to the network-card of my notebook. i will try out cable connection with the router and report it later here.

unfortunately it's absolut correct. i couldn't believe that there's a large difference in transfer rate between cable and wlan 802.11 n. but today i transfered a 4 GB file via cable with 50 MB/s and via wlan with 5 MB/s. so if you are transfering a lot of data use a cable and for other application wlan is adequate.

I just got a DS212j yesterday and so far I love it.

However, I've ran into one problem while trying to transfer my data to the new device. I'm on a gigabit network (both my PC, the NAS, and the two switches in-between), but my transfer speeds in Windows are around 12MB/s. Ridiculously slow.

I have Windows, Mac, and NFS sharing turned on. I've left the Network settings pretty much alone (using DHCP instead of Static. Didn't mess w/ Jumbo Frame because I don't really know what that does).

The DSM web UI itself is very speedy, but if I use the built-in FileStation to transfer it's even slower, around 200KB/s. I know from my work that LAN-based HTTP uploads can go way faster than that, so I have no idea what's up w/ that either. Browser is Chrome.

In the Resource monitor, my CPU is only 50% in use and RAM usage is around 30%. I've enabled a lot of services (iTunes server, Photo Station, etc) but left most stuff at their defaults.

Any idea what could be causing these really slow speeds?

12 MB/s is typical for a 100 mbit connection.
Check your connection in DSM: Control Panel | System | Network. Tab network interface.
Network status should show: 1000, full duplex, MTU 1500
If not, there might be a bad ethernet cable.
You could also test with both PC and DS attached directly to the router to rule out a possible switch problem.

That's exactly what it says. It also says that on my PC.

I did get 1gbps to my old NAS over the same cables, which is what had me thinking it may be a config problem w/ the Synology. Hmm...

I'm running into a similar problem, except my DS212 is reporting a 100 connection, while in reality it's plugged into a gigabit router (DIR-655). I have a DNS-323 plugged into the same router and it's reporting a 1000 connection. I've even forced the router to only allow gigabit connections, but the DS212 is still reporting a 100 connection.

Only getting 6.5mb/s on a copy from the DNS-323 to the DS212. I connected directly to the DNS-323 from the DS212 and initiated the copy. It's not flowing through a PC mapped drive or anything.

At this rate I'm looking at another 48 hours to complete the 1.3TB data migration (24 hours into it).

Tried switching ports - using the cable that came packaged with the DS212. No change. It seems the DS212 is really good at dealing with routers being rebooted and cables being unplugged, while managing the download. It hasn't hiccuped yet, picking up where it left off every time. I'm tempted to reboot the DS212 itself.

Hello to all,

just experiencing a download speed issue with DS212j. I have TP-link WD1043ND router, which has Gbit ethernet ports and Gbit network card in my main computer. Upload to NAS is just fine, running around 50MB/s without a problem. But when trying to download a file back to computer, the speed is 5 times slower and it looks like if there was 100Mbit network connection only. Few days ago I tried to update my router firmware to the latest version and suddenly download speeds rised up to 80MB/s, everything looked just fine and worked the whole evening. Unfortunately, after next few days (I didn´t use the NAS since, nor did I change anything with it or with my computer) the download speed problem is back as it was before. Tried to reset the router, repatch the firmware, reset NAS settings to factory defaults, tried to update network card driver, no success.

Seems like the source of the problem is finally NAS itself, as with the others in this thread. What a bad luck, after I found out how to solve the thumbnails issue and thought I´ll be ok, this trouble happens .

After much work and help from Synology this was the problem with my set up:-

viewtopic.php?f=14&t=48109

Everything now working as expected and has been for a couple of months. Strange where problems might lurk.

Well, I really don´t understand it, but today after hour or two of playing with my router and NAS settings again my download speeds are back on track, oscillating between 60-80MB/s with a few peaks up to 90 and some drops to 40-50.

I noticed 2 things, though:

1. while copying, when I started messing with the computer (e.g. playing mp3 in foobar), the speed dropped rapidly, in the end down to 14MB/s while rising back after stopping it.
2. when I tried to copy many movies, the speed slowly decreased from 80MB/s to steady 50-60, but when copying them separately, the values remained around 80MB/s for each file.

Anyway, I hope history won't repeat itself in this case . Also, if I'd come across any idea what was the source of my problem, I'll post it.

OK, I don´t want to spoil it for me, but seems like my DL speed problem is gone.

Here is what I´ve done, though I probably don´t remember the exact order of those steps, but I try my best:

1. Looked for network status in the NAS network settings, it showed 1000 duplex full, to be sure checked through ssh to router and ethtool command as described here http://wiki.openelec.tv/index.php?title=Configuring_Gigabit_Ethernet , with the same results.

2. Changed auto-negotiation in the computer network card settings from auto to 1Gbit.

3. Set static IP address for the NAS through DHCP server and MAC filtering in the router settings, left automatic network configuration (DHCP) in the NAS network settings.

4. Reset the router.

That´s it, after this everything works just fine, DL 80-90 MB/s, UL 40-50 MB/s.

One more thing. Should anyone have Logitech Squeezebox Classic, be sure to check your router for potential IP conflict. In my case, even when I set one static IP with MAC of the Squeezebox, in the address reservation list it surprisingly showed that the Squeezebox took a different IP on its own (everytime the same one, but it wasn´t the NAS IP). So I changed it permanently to the other one. Not really sure, maybe this was part of my problem, too.

Hope this helps someone!

Hello everyone

I just have my NAS from yesterday and I'm really happy with it, just not with the write/reading speed.
I read this is from the cache etc. that Synology DSM 4.0 doesn't support.

Know I saw here that you can downgrade, I want to do method 1. But unfortunately I don't know where I can find "/etc.defaults/VERSION".

Everyone who can help me or even tries, I'll appreciate it!

[Str3ss]

Anyway.. Here is my netwerk setup:
Modem is connected to a Powerline (dLAN 500mbps AvMini) to another powerline in my room (same ofcourse), this one with a Gigabit switch (Sitecom Network Giga Switch 5 port LN-120) and this to my PS3, PC and NAS (DS212j). Everything that is wired are with Cat5e cables.

My write speed: 33.8 - 35MB/s
My read speed (most important & horrible speed): 37MB/s - 40.5MB/s

NAS: Synology DS212j
HDD: 1x ST2000DM001 (2TB) with SHR

So how can I fix it, that it goes faster? My read is so slow..

Thanks in advance!
