Upload speed to Droplet from Windows 10 extremely slow

Posted on August 18, 2018

As the title says. I have just tried, a new fresh Droplet, with Debian 9.5, a new fresh Windows 10 1803 x64 installation. TCP uploads, SCP, SFTP, HTTPS, etc, are extremely slow, like 5Mbps.

It’s not my internet connection, it’s not any CPU/RAM/Disk bottleneck, it’s not my latency or connection to DO’s LON servers, it’s not any traceroute problem, it’s not anything I installed because everything is vanilla.

What’s happening here?

Digital Ocean support is not listening at all and haven’t been able to fix the issue in the past 3 days. If I use Debian 9 on the same Windows 10 computer where I have the problem, everything’s fine, upload speed is as far as it can go. So it’s not my computer either. This problem also shows up on other computers with Windows 10. Can anyone reproduce this problem? Download speeds from Droplet to W10 are ok.

I’m still seeing this as well. 12 - 20 KiB/s from Windows machines in my house, 3 - 5 MiB/s from Linux machines. Tried multiple machines and different types of software, it’s applying not just to SFTP/SSH but to HTTP and everything. Windows users can’t properly browse sites hosted on my Ubuntu droplet, it’s legitimately unusable.

Some testing:

Uploading 143 MB file through SFTP, from Windows 10, to new Droplets:

Ubuntu 16.04.4 x64 ·Kernel: 4.4.0-131 ·Min speed: 500 KB/s ·Time: 4m7s

Ubuntu 18.04 x64 ·Kernel: 4.15.0-30 ·Min speed: 3.5 MB/s ·Time: 38s

Debian 8.10 x64 ·Kernel: 3.16.0-5 ·Min speed: 3.5 MB/s ·Time: 38s

Debian 9.3 x64 ·Kernel: 4.9.0-7 ·Min speed: 490 KB/s ·Time: 4m37s

This is huge, Ubuntu 16.04.x and Debian 9.x which are the default OSs for Ubuntu and Debian Droplets are the slowest. Are all Windows clients/users having this upload limit issue to Droplets??
