This image shows the impact of the preferences listed in comment 83 on my personal machine: top is with JIT, bottom is without JIT. We can see that for the specific case of loading youtube.com 5 times in Firefox: - `MsMpEng.exe` total CPU time decreases from 16s to 6s by disabling JIT in Firefox; - `firefox.exe` total CPU time for the most active processes is around 23.5s in both cases, it doesn't change significantly when using or not using JIT in Firefox.
