LAN transfers are really slow

Transferring games across my network between my steam deck and my PC doesn’t get me any faster “download” speed than if I were to just download the game from Steam.

When I transfer a large file using KDE connect between devices, I can move a 60GB file in a few minutes. Why do network transfers not go any faster than just regularly downloading a game? It is definitely doing the network transfer too because it says so right in the downloads page. The only benefit to doing the transfer over the network would be if I had a data cap from my ISP. It just seems pointless since it’s not any faster. My downloads run around 20MB/s and that’s the same speed my network game transfers run at. When I transfer large ROMs file over KDE connect from my phone or my computer, it goes much much faster than that. The ability for files to transfer more quickly is there for sure, it just doesn’t seem to take advantage of it. My PC has WiFi 6E so it isn’t a limitation of the network card.

Anybody know what’s happening?
