Hi Jeff,

We're aware of some issues with upload speed to Google Drive. I assume in your case the upload is using HTTP/3, right?

We're aware of some issues with upload speed to Google Drive. I assume in your case the upload is using HTTP/3, right?

What's the best way to determine whether it's using HTTP/3?

Flags: needinfo?(valentin.gosu)

I think it should be visible in devtools, or since bug 1938620 it should also be present in the profiler.
In any case, our leading theory right now is that this is related to our congestion control algorithm that we use for QUIC.

Yes. This seems to be with HTTP/3

What's the plan for fixing it?

This should have stayed in Web Compatibility

We're still investigating it. Probably related to our congestion control implementation in QUIC. Work ongoing in bug 1852924.
