Baking physics not using much CPU power

So, I’m currently baking an extremely complicated physics scene (5000+ link chain mail), 128 physics steps, 8 solver steps, and it isn’t taking much CPU at all. It’s currently 8% done (about 100 frames in), but the CPU use is hovering around 14%, with almost no GPU use. Why would this be? Process priority’s high. Is there any way to “force” blender to use 100% of the CPU, or is there another limiting factor (L3 cache, HDD speed, etc). Thanks a lot!

Baking physics is not multithreaded so if you have a multi core cpu it won’t be able to use all of them
