SW2019 + Hypermill only using ~15% of CPU

Hi all,

I am using Solidworks 2019 in combination with Hypermill 2019. When I run calculations for my tool paths it takes longer than it should, when looking at task manager my CPU utilization is only at ~10-20%. SW is using 5-6% and the Hypermill tool is also using around 5-6%. Both are set to "High" priority and the affinity is set to use all cores. I'm using an Intel i9 7900X and I want to take advantage of all of its power if I can. Is this a SW limitation or is there a way for me to optimize this process?

Thank you
