Today I experimented with background rendering on 2018.12. I've mostly used background transcoding on 8_9_4 and earlier.
Yesterday I posted about seeing 1,300% Cpu usage during the render of my upper track safe color limit. Today I tried the same thing on sections clicking render in the background. Depending on what I was doing in Avid the TransferService worker hovered around 1,000 to 1,100% cpu usage if I was inactive in Avid for several seconds. When I started playback in Avid of rendered sections of my 4096_2160 sequence of DNxHRHQX media the TransferService worker would drop down to aroun 750% cpu usage. That all makes sense.
Just to see I started a foreground normal render of a different section of the safe color limit. Then the TransferService worker would hang around 750 to 800% cpu usage and Avid Media Composer would hover around 1,000 to 1,100% cpu usage. This seems to indicate that where as a normal solo foreground render uses 1,300% cpu usage a combo render in background and foreground uses a sum total of approx 1,900% cpu usage. With a foreground render the Avid is idle other than the render which is normal behavior.
I don't know if this behavior has existed in the latter MC versions as I've virtually never used background render in the past but something to make the progress bar more interesting.

I'm noticing on my MacPro mid 2010 upgraded to 12Core 3.33GHz OS 10.12.6 ATI Radeon HD 5770 1024MB system in a Rec 709 4096x2160 project with DNxHRHQX media rendering to ProResHQ is using around 1,300% cpu. I haven't checked Activity monitor for cpu% usage during renders in a long time. I've been on MC 8_9_4 and am now on 2018.12. I know that the handling of DPX media was greatly improved in this latest and I believe the last few releases.
Curious if the cpu usage I'm seeing with rendering is new to these latest releases or has it been going on for a while and I just didn't notice. I know Transcoding got updated to use a lot more cpu quite a while back. Anybody know the history of rendering cpu usage in the last few rounds of Avid releases?
