That was with very high quality encoding. This is still AV1 0.2 fps isn't too bad, to be honest.

Using faster settings (preset 5) I was able to achieve 4 fps, which is quite fast for 1080p AV1 with 4 cores. The fastest preset delivers 12 fps for me.

Regarding point 2, I think that's exactly what SVT AV1 is designed for, particularly when encoding multiple bitrates in parallel for ABR delivery. A full ABR ladder encoded live appears to be one of the goals of the project. libaom has terrible threading last I checked, as many big OTT VOD services will run encodes single threaded.
