That may be, but Brendan Gregg is not a junior flipping switches, and a resource like this can help others do smart tuning.

- dijit 3y agoI didnt expect anyone would read my comment that way. No, Brendan Gregg is certainly no junior. The issue is that people take his advice as law and do not read further. I, myself, remember flipping random switches because a (book) resource said that it would unlock performance. I’m suggesting that taking the time to understand performance properly is ideal and I am attempting to urge people to properly invest the time. Then I am lamenting the fact that we do not actually have time over because there’s so much smushing of responsibilities.
- eduction 3y agoAh fair enough, sorry if I misunderstood!
- traceroute66 3y ago> Brendan Gregg is not a junior flipping switches That's because Brendan Gregg doesn't flip switches, he shouts at hard drives[1]. ;-) [1] https://www.youtube.com/watch?v=tDacjrSCeq4 https://www.youtube.com/watch?v=tDacjrSCeq4

- cinntaile 3y agoDoes it work?
- bornfreddy 3y agoNot GP, but no, it doesn't. It appears to work but then side effects get much worse. Taking the time to understand and to tweak the right settings, I mean, explain, is much better in the long run.
