file transfer to ubuntu 16.04 is really slow.

Linux Basics Ubuntu 16.04

File transfer to my linux droplet from my mac is really slow, we are talking 2-7 KB/s.
The first few files have a upload file of 500-1000 KB/s.
My internet speed is 35 download and 5.5 upload.
droplet is hosted in germany and im from denmark.

What my command look like

scp -r -v /file USERNAME@HOST:/path

i have added these lines to ssh_config file, because i couldnt upload files to my droplet, so i found this fix on this website

ServerAliveInterval 30
ServerAliveCountMax 5

So my question is: How do i fix this?

This is my first ever experience with linux, so please keep that in mind :)
Thank you for your time.

    Any found on the reason? I’m experiencing the same problem. My first upload started at 2,2Mb/s and finished at 400Kb/s, which was acceptable. My current upload which I’m struggling with runs at 40-17Kb/s. I initiated it with the command: 

    scp /path/to/my/file USERNAME@HOST:/path

    Any ideas on the subject?

Hello, @Syhler

I will recommend you to use rsync instead of scp as it’s proven to be a lot faster.

scp basically reads the source file and writes it to the destination. It performs a plain linear copy, locally, or over a network.

rsync also copies files locally or over a network. But it employs a special delta transfer algorithm and a few optimizations to make the operation a lot faster.

Hope this helps

Regards,
Alex
