Microsoft Edge throttling upload because of latency

I recently changed from Chrome to Microsoft Edge because the other was hogging my memory and making my system unstable. Unfortunately, I noticed that my upload speed has reduced. 

Basically, when I do a speed test using speedtest.net, my speed is always 20/20 to the ISP itself with a ping of about 9ms. However, once I try a server half the world away (usually London), ping goes to 100ms, download speed is still 20 but the upload goes down to about 5.

I thought my ISP was playing a fast one so I caused a ruckus. Over a period of 4 visits - we tried all the known tricks and the problem never went away. We removed my home wifi router, connected directly, nothing worked.

Until the engineer had the smart idea of trying Chrome (the abandoned old friend) on my laptop, and boom, the speed was 20/20. Then we tried Opera, good speed to London as well. I got my daughter's laptop into the mix, 20/20 to London as well. 

It was apparent that Edge was to blame. I humbly apologized to my ISP, Cobranet.

A similar problem has been reported here for an Xbox Upload speed issue and high ping - Microsoft Community

My question is, what's the problem? I love my Edge because it's stable and I don't want to use Chrome again.

    Thanks for your opinion about this. However, as far as I'm concerned, and doing tests concurrently, this is Edge and nothing else. 

    It's just impossible that the 90% variation in speed only happens when I'm testing on the Edge browser and that it only happens for destinations with a ping of more than 30ms.

    Just to prove to myself that I'm not mad, stupid, or both, I ran the tests right now and exactly the same variation of results.

    But if the speed test is done within a target server within the country, the result from both Chrome and Edge are similar.

    For one i just did those tests with 3 browsers and 3 servers each just to rule this out.

    Secondly i have done enough of those tests throughout my life to know that the results can vary by 90% of base value in the same hour.

    Believe me: The reason is not Edge.

    I currently have this problem, I get speed test of 40 down and 4.5 up with chrome and 40 down and socket failure or 40 down and 0.25 up with edge.

    I'm on satellite so I have 650 ping. but get expected numbers with chrome.

    I went through all the trouble shooting, even wired the house with ethernet to eliminate all outside interference but the problem remains.

    I stumbled onto the issue that it is Edge being the source of the problem.

    Please fix it, I don't want to use chrome.

    thank you

    I know this was posted quite a while ago, but it looks like this thread has gotten some views recently. Hence, I wanted to check in and see if you (or anyone landing on this thread via search) are still seeing this behavior on the latest version of Microsoft Edge.

    Make sure to include this 100ms ping threshold as if i select london (i am based in germany) i get the same upload speed for Edge as i get for other browsers.

    Only when its a far away location with high ping the upload speed stalls.

    I have the same issue (ie: similar download speed but much slower upload speed on Edge), but my ping is around 44ms. So its not exclusively an issue with a 100ms ping threshold

    Ok i tested again with servers which offer more than 100ms ping to my location.

    And the result surprises me more as you would think.

    Indeed Edge manages to only get 5mbit of upload speed (download unaffected) to those servers while other browsers manage to get 9-10 mbit.

    I think you found an so far undiscovered bug and it is time to file it to MS:

    Use the feedback hub to report the problem to Microsoft so it can be fixed.
