Filetransfer networkshare fast (1Gbits) SFTP slow 120Mbits)

[gasemans]

Hi all

 

I am running XPenology on a N40L with 5 4TB harddrives.

I have setup a raid 5 with a 1.45TB Netto storage.

 

I shared a folder and tested the transfer within the local network and i get a perfect speed between 80 and 113 MB per sec.

 

Now i have setup SFTP and connected to the FTP on the internal network.

When i transfer the data i will receive a transfer rate of 10 to 15MB per sec.

 

I have not set a max transferrate @ all so i would have expected a rate of 50MB per sec atleast.

But that isnt happening.

 

During the test i used the same file (1 50GB binary file)

 

All data is being send from the same machine. (data file is on a massive SSD)

 

Only differnts i now about is the protocol and i used the FTP to connect to IP

And accessed the share through DNS name.

 

 

Any one who has an idea what is going on and how to fix it?

 

I need more speed because i am using it as a backup for a small company.

My internetline is a 500Mbits and the small company has a Gbit line.
