I still managed to read the whole thing. Quite fascinating, really, considering the lengths he went into tracking the ancient (1993) patch that turned CPU load averages into whole system load averages.
I am beginning to suspect that Brendan Gregg is not a real person, but a collection of extremely talented individuals publishing under a pseudonym. ( https://en.wikipedia.org/wiki/Nicolas_Bourbaki )
PS: yes this is meant to be a compliment on the prolific output on performance related topics that Greg puts up on his page.
I wonder what a what a good solution for aggregating all of this data and making it more easily searchable next time would look like, and if there's anyone working on it.
It seems like such a waste to have it scattered all over the place, and for all the author's hard work in tracking it down to go to waste.
