Is anybody using SMB over QUIC over the Internet

I'm trying to set up a proof of concept, and while it works locally, performance over the internet leaves much to be desired when compared against accessing those same shares via traditional SMB over a VPN. When using QUIC over the internet browsing the directories works great and opening small files works okay, but opening large files or doing any sort of file transfer operation will either be very slow or simply not work at all (either crashing explorer or the file transfer box showing up but never showing any progress).

Environment details:

Server 2025 running in a Hyper-V VM

Windows 11 24H2 and Windows 11 Insider Preview running on various model Dell laptops
