Google Fi, along with many other mobile telecoms, tend to limit the speed that you can attain from tethering, especially when roaming. Since computers don’t usually expect this, programs tend to misbehave on such metered connections.
In fact, I built a tool to specifically circumvent this: https://github.com/nneonneo/iOS-SOCKS-Server. It provides a SOCKS proxy through which you can tunnel any TCP connection, and have the connection appear to originate from your phone (and thus not be subject to the tethering rate limit). I used this when I was in China recently (2019).
