Very slow upload via Cloud Sync

[fanzuga]

Hi, all.

 

I try to configure file synchronization between my NAS and cloud accounts. Downloading files from cloud to the NAS is fine – about 50 Mbit / sec.  Upload and download via LAN are also awesome - about 70 Mbit / sec.

 

But upload via Cloud Sync – only 27-30 Kbit / sec. (Yes, Kilobits not Megabits).

 

Upload via browser is quite good – about 20 Mbits, so I guess this is not hardware or ISP problem. Also I tried different cloud providers (box.com, Yandex Disk, Mail.ru Cloud WebDAV) and the situation is the same – good download and very slow upload.

 

My configuration: DSM 6.1.7-15284 on MB Intel D945GCLF2 + Atom 330.

 

Has anyone achieved normal upload speed via Cloud Sync?

 

So you have any idea what the problem could be?

 

Thanks at advance.
