From the top of the article (added?) "I summarized this case study at Kernel Recipes in 2017." The bottom of the article notes that his book Systems Performance 2nd Edition is 45% off until 9/13. Edit: looks like the comments about "didn't I see this a few years ago?" have been deleted.

Not added, but maybe I'll add something extra to make it more clear. I have a backlog of interesting case studies I'm trying to find time to share.

  Not sure if you're comfortable sharing it, but if so, how many copies have you been able to sell? Also, any idea how something like safari online impacts those numbers? Thanks again for the book, it's an amazing read that I recommend to anyone that is interested in the area.

    Systems Performance 1st edition sold over 10k copies for the English edition, and that was half Solaris when it was falling in market share. 2nd edition is more Linux focused, and shows how eBPF fits into the toolset, so I'd assume it'll sell more than 10k. (The publisher has been changing their author's portal and I haven't been able to login for months now, so I don't know the current numbers for 2nd Edition.) Various companies make it required or recommended reading for new engineers, which helps a lot (thanks!). How much pirated PDFs hurt these books I'm not sure, maybe a little, maybe a lot. With my BPF book, a "rough cut" was published on Safari and then that did the rounds as the PDF (and still does) even though it was unfinished and buggy. That's what annoyed me the most about it, was that people were reading a broken version and may be thinking it's the final version. Thanks for getting and recommending it!
