Re: Slow Upload Speed - its back - Makes gaming Impossible

Yes I've seen others with this whats odd is that in order the download @350Mb you must send a bit back and 0.22Mb is not enough but that speed is at full size packets when you download you send small packets back at xxMb so clearly that works or you have slow download speed too.
I'm pretty sure VM are doing something to allow small packets to have higher Priority on the upstream not that VM will tell us.
You can do some tests to change the MTU of the PC netsh interface ipv4 set interface "Ethernet" mtu=1500
The “Ethernet” maybe different use netsh interface ipv4 show interface to find it then if you lower MTU to say 1400 you can check it here https://www.speedguide.net/analyzer.php then run a speed test to see if you can get a faster upload not that it should just that this is a VM QoS/BWM problem.
Edit Also could be in the downstream small packets to have low Priority...
