Hello; I am new here and far from me to be unsympathetic, but I made some tests with and without VPN (proton VPN here), and my results are prompting me to say the same as in
Hi there,
I use a VPN to connect to my office network, over 4G, with the Strongswan app.
Here’s the weird thing:
connection speeds are great when I use my PC (PC → smartphone (USB Tether) → VPN through 4G → office server): ~60 Mbps
connection speeds are so slow they are barely usable when my smartphone is used directly (smartphone → VPN through 4G → office server): <1MBps
So far I haven’t bee able to find something relevant on the Internet, any idea would be appreciated,
Thanks.
I also made a simpler test:
Phone + VPN → 1.7 Mbps
Phone (hotspot) → Tablet + VPN → 18 Mbps
This last easier to reproduce.
