Slow FTP speeds with DS212j

Postby kdmitchell27 » Tue May 29, 2012 6:30 pm

Hello,

I've been testing the FTP speeds on my DS212j and I'm kind of disappointed. Testing from both of my cloud servers and 1 physical server I can only reach up to 1MB/s on transfer (in/out) to the NAS.

Thinking that perhaps it may be an issue with connection, though I doubt it as my FTP speeds routing directly to my Win2k8 VM that is housed on the same NAS is hitting speeds up to 3-4 MB/S. Even still I tested this internally and sure enough the same issue arose. Max connection was about 1MB/s, where a UNC transfer capped out at 12MB/s.

It's bad enough I can't mount the NAS and use it with my FTP server (Permission issues) however it seems that this NAS is limit capped when it comes to FTP. I noticed several other threads here experiencing the same issue but no reply as to if the issue was resolved or not.

Anybody?

I've been using FTP - from/to my DS212j with FileZilla and lftp - over a homeplug LAN and I'm pretty sure I'm getting more than 1MB/s ... ? Will have a look this evening.

EDIT: Oh, I'm using SFTP server, maybe that makes a difference ??

Used method 1, but 3 also seems to work.

Technically due SFTP encrpyting the connection it would be slower, but in this cause it's definitely something wrong with the NAS.

I contacted support and all they said was make sure the FTP restriction wasn't place... don't you think I'd check that first?

There are tons of threads on this forum about slow transfer speeds via FTP and noone has gotten an answer as to what's happening. All I know is that transferring a 600MB over a 100MB network should not cap at 400KB/s, that's just sadly unheard off.

Testing with Teracopy vs FTP, Teracopy moved a 600MB file in 53 seconds... ftp is still going on 20 minutes.

Sigh, the more I look into this NAS the more I regrey purchasing it.

That sounds wrong ... I regularly copy files, TV episodes of about 600-700MB from my DS to the media-player. Initiated the transfer from both ends (installed 'lftp' with ipkg on the DS), so I've used 'put' and 'get' and the transfer never takes more than about 3 minutes (over homeplugs, so with less than 100Mbps).

What is the 'FTP restriction' that Support mentions ??
EDIT: oh I see now ; I've got nothing checked there, no limit on connections or bandwidth restrictions.

Agreed. Though I've been getting the dreaded "Improper Shutdown" errors more and more and the unit is barely 2 months old. Think it may be defective and I already contacted Synology regarding this.

Meanwhile I've checked the network and cpu logs and they all are good while transfer via FTP. I'm at a loss here.

I just went ahead and created an iSCSI LUN and connected it to my Windows 2008 server and then setup a FTP user. Connected via FTP on my local LAN and remote LANS to do some transfers;

Verdict says!

7MB/S from remote server
12MB/S from local server

So it seems there's something going on with the either the FTP software or it could be block size, which I don't think that's the case. However in any event I'll just resize the LUN and keep iSCSI in affect. As long as I can map to them it's all good.

Did a little test with a 600MB episode ; initiated a 'ftpget' from my mediaplayer (PlayonHD) to the DS212j with standard FTP ... took about 4 minutes, not bad for homeplugs.
I'm not using iSCSI or anything.
