Windows 10 slow upload speed

Post by hlstriker »

I am using Windows 10 Pro at a datacenter on a 1 Gigabit port and the upload speed of that computer seems to significantly degrade when latency rises. I do not think it's the routing causing the degradation as there is another Linux machine on the same network that does not have this issue even when taking the same routes.

For example:
  • If I do a speedtest and get 5ms latency I will download and upload at about 950 Mbps.
  • If I do a speedtest and get 50ms latency I will download at 950 Mbps and upload at 30 Mbps.
I've been searching all over the internet to hopefully find a solution but nothing has worked so far. I installed TCP Optimizer v4.0.1 and tried quite a few different settings including the optimal option at 100+Mbps but nothing seemed to make a difference. Hopefully someone has an idea of what the problem could be as I don't have a clue.

Here is the log generated from TCP Optimizer:

Does this even sound like an issue from the computer or does it sound more like an issue along the route itself?

Any thoughts on this? It's been a few weeks now and I still can't figure it out :(

If you are getting a speed test with 5ms latency, the server is really close to you, most likely your ISP (you can do a traceroute to verify). This means, you are testing the connection between you and your ISP.

If you get a speed test with 50+ms latency, your transfers are out on the internet, and actually depend on the backbones of your ISP, their peering arrangements, and what they allocate to you. This will almost always be much slower, especially for residential connections where the bandwidth is oversubscribed 20-25 times usually.
