( Please provide the question this one duplicates. I'm disappointed I couldn't find it. )

My development machine is "slow". I wait on it "a lot".

I've been asked by decision makers who want to help to fairly and accurately measure that time. How do you quantify the amount of time you spend waiting on the computer (during compiles, waiting for apps to open every day, etc).

Is there software which effectively reports on this sort of thing? Is there an OS metric (I/O something something, pagefile swapping frequency, etc, etc) that captures and communicates this particularly well? Some sort of benchmark you'd recommend me testing against?
