If a particular prefix list of stack frames is responsible for one 20 second hang for one in 10 users every 5 hours (pretending all users use Nightly for the same number of hours per day), you'll see a value of 20,000 / 10 / 5 == 400ms/h. > > Should the left column of the profiles report the time in ms/h instead > of unit-less % ? > That's a good suggestion.

Maybe if we end up going with RAPPOR we'll be able to see some aggregate stats on hanginess of particular domains though. Or we could prompt Nightly users to opt into sending more sensitive information, but that brings biases with it. > > > Can we have a larger history of hangs per signatures?
