I see the following issue: if I download some file, the download starts with the whole speed of the channel, but the speed quickly starts to drop. This happens with any download, I try files here (release, beta, development snapshot), Sourceforge, anything else. One can see this in the session information window, network gadget.
This doesn't happen directly on the host and from 7.0.20 / 21 versions with same VM. The only difference is a new network engine with IPv6 support or IPv6 somehow itself.
Maybe it's a ping trouble. If I run an internet speed test in the VM, the speed drop happens way slower. I can download to the virtual HDD in the VM or to the shared folder - this also doesn't matter for this issue.
My combination is Windows 10 host and Windows 11 guest with latest updates.
Maybe there is a connection with "VirtualBox VM 7.1.0_BETA2 r164448 IPv6 NAT "no route" error" issue?

Re: Traffic shaping problems with NAT
It is very possible.Maybe there is a connection with "VirtualBox VM 7.1.0_BETA2 r164448 IPv6 NAT "no route" error" issue?
Do have Internet with IPv6?
Try to disable IPv6 in the guest operating system

Re: Traffic shaping problems with NAT
Disabling IPv6 in the guest OS didn't help. Vice versa: now the download already starts at a slow speed and tries to speed up a little, but never achieves the whole speed of the channel. So the problem isn't IPv6, but the whole new network NAT stack.
It looks like probably some buffer is filled initially at full speed and has some problems to fill this buffer afterward, as download continues?
