Hi! Thank you both for your help.
I solved this issue 2 days ago, I had a problem in my Windows 10 desktop and I investigated it for a few days till I found this:
 
https://stackoverflow.com/questions/10694244/sending-data-from-windows-is-slow-over-any-network-with-high-latency-but-linux-i
 
I wrote this on my CMD: netsh interface tcp set global autotuninglevel=normal
And it worked!
Now if I run the test on my desktop pc I have more than 30Mbps and before I had 3. I don't know why Windows was configured in that way.

Have a nice day and thank you for your time!

You are a god for finding this cmd, instantly triples my download. I was trying to figure out why my pc was getting a 3rd of the download I was paying for for 3 months!
 

Thank you SO much. This fixed my speed.
I had this problem over a year ago and ended up just reinstalling Windows to fix it. It came back and I was dreading doing that again :P

Thank you JereSalo! this works for me too. only one of my PC has a slow speed, I been looking for the reason for few month, but you solved my issue!
