Hello,

I’ve recently answered the same question here:

https://www.digitalocean.com/community/questions/why-the-vast-differences-in-upload-and-download-speeds

It seems to be a problem with the version that comes by default from the Ubuntu repos.

I’ve just tested that and indeed I got the same results. Then I used the strace command to strace the process and I noticed that during the Upload tests the connections to speedtest.net were timing out.

I would recommend following the steps from the answer above on how to get the latest version which will work as expected.

Best,
Bobby
