Ubuntu 16.04.3: Handbrake not 100% of all CPU cores (using stebbins ppa)

edit: 1080p source
Hello. Has anyone used hanbrake recently on a linux and a windows-based setup?
I have a dual CPU Xeon (8 cores per CPU with HT) setup here with 64GB RAM. I noticed that on Windows, handbrake will run a consistent 100% on all CPU cores (including the HT ones). While on Linux, I don't see any cores running at 100%. The highest I see are at around 85% and only a few of them. and the usage seems to go up/down unlike on Windows.
Is this perhaps a limitation of the CPU governor/scheduler in Linux? I have installed the intel microcode.
In both Windows and Linux, I was using the built-in SuperHQ1080p30 Surround profile.
Here's the activity log of the currently running encoding: https://pastebin.com/raw/tFnrAm94
Any ideas on how to improve performance? Thanks
