I tried this and it doesn't work. Turns out my MacBook was throttling to 30% due to overheating. This happens more frequently if you drive the GPU with an external monitor. Unfortunately the OS does nothing to notify you of overheating and throttling, which is an insanely stupid oversight by apple. I only found out because I noticed that the computer ran fine while running the AC, so I installed an app through Brew called "Hot" which tells you temperature and throttling percentage, and confirmed that this was indeed problem.
This happens when the room is over 80 degrees Fahrenheit, even when the CPU is at 3% utilization. Can't find root cause, or if this is even considered abnormal, but the laptop is defective in my opinion.
