SOLVED: i3-12100 transcoding performance (Expectation vs reality?)

[radiator]

I recently upgraded my home server to an i3-12100 to enable hardware transcoding.  During my research on which CPU to choose, I often saw comments about the recent 100-series CPUs that said things like, "just get the 100, it transcodes 3-4 streams at once without breaking a sweat"

I got hardware transcoding set up and configured and did some testing using the Jellyfin web client to force transcoding.  One 4k stream does great, two start to struggle, and three is not happening.  I'm curious how my experience lines up with others' and if there are settings I could change to make transcoding use fewer resources.  I'm including the ffmpeg log and a screenshot of intel_gpu_top (attached) while transcoding just one 4k stream.
