Hi, I'm the author. I'm glad you enjoyed it, and pleasantly surprised that Tanel posted it already. I was right in the middle of posting it myself an hour ago when I noticed it had been posted and had fostered a discussion already :)
Thanks for writing this up and doing the work preceding the writeup. Every time I read your articles, I learn something important and new (and I consider myself pretty good in the Linux perf/troubleshooting space :-)
Brilliant, thank you! I used to be a performance engineer many moons ago & love this content. Makes me want to get back into it!
