> My dream is to turn computer performance analysis into a science, one where we can completely understand the performance of everything: of applications, libraries, kernels, hypervisors, firmware, and hardware.

Reminds me of Bret Victor's Inventing on Principle (2012), https://www.youtube-nocookie.com/embed/PUv66718DII

I didn’t expect this to be so… literal.

Wait till you find out about "parking" your drives

It worked too, you could replicate this easily yourself. A bit harder with an SSD ;)

A video posted by Bryan Cantrill no less.

At the time of the video they were working on the "Fishworks"† project:

† A play on Lockheed Martin's "Skunkworks".

Forgot about the video and didn’t realize it’s the same person. Also reminded me of this 2016 incident that happened in an ING data center https://www.bbc.com/news/technology-37337868.amp

I have to sit down for a minute...

I wonder for how long they were debugging the performance issue, when screaming at a server rack seemed a worthwhile idea
