What do these do?

Today I found these two options in Processor power management but I don't know what they do on the laptop. I've tried searching on Google but the info is pretty vague. Hope someone can explain it to me. Thanks

What CPU does this system have?

Processor performance increase threshold is the maximum usage percentage of your CPU before your OS requests that the CPU goes faster. This is probably triggered if any core goes above that threshold, not necessarily the whole CPU.

 

Processor performance decrease threshold is the minimum usage percentage of your CPU that will prevent the OS from requesting that the CPU goes slower to save power. This probably requires all cores to be below that threshold.

As @BobVonBobmentioned and linked, they are settings to control the CPU clock boosting algorithm.

Basically, it is to fine tune the CPU behaviors, so that you don't fall onto a situation where a program is doing something demanding, but not enough for the CPU to clock faster, which result in taking more time than it should. If it doesn't bother you: Great more battery life! If it does, then you can adjust the setting to exchange battery life for more performance.
