If it looks like this, then nobody cares. Clearly the user in question
never actually cared about performance, and you SHOULD NOT then say
"let's optimize this that nobody cares about":.
Yury, I spend an inordinate amount of time just double-checking your
patches. I ended up having to basically undo one of them just days
ago.
New rule: before you send some optimization, you need to have NUMBERS.
Some kind of "look, this code is visible in profiles, so we actually care".
Because without numbers, I'm just not going to pull anything from you.
These insane inlines for things that don't matter need to stop.
And if they *DO* matter, you need to show that they matter.
