I have Synology DS212j and I'm getting REALLY slow transfer speed, about ~10MB/s.

I used following knowledge base in order to troubleshoot it:

What should I do if file transfers are slow? - FAQ - Synology - Network Attached Storage (NAS)

  1. Network Status - 1000 Mbps, Full duplex, MTU 1500
  2. Storage Manager - no problem
  3. My computer's CPU - no problem.

Please advise.

  • Lots of little files will copy a lot more slowly than fewer large files. Are you using SMB, HTTP, or something else? SMB will always be slower than something like HTTP. I've seen a huge difference in speed if I upload files through the HTTP GUI vs using a mounted SMB on my own Synology NAS. – David W May 19 '15 at 14:08
  • Check the Ethernet cable, it might be CAT5, thus capping you at about 12.5 MB/s. – Peter Aug 10 '15 at 01:10
  • I'm using `CAT5E` Ethernet cable. – alexus Aug 10 '15 at 14:13

"slow transfer speed" - was due to enabled encryption, as soon as I disabled encryption speed went up substantially.

  • For future reference, was SMB encryption enabled, or shared folder encryption? What exactly did you disable? – Wouter Apr 16 '16 at 16:54

    @wouter I believe it was `Shared Folder`, I don't think "SMB encryption" even exists) – alexus Apr 16 '16 at 17:09
