That's cool. Right now I'm at the stage "I know how to profile, I can identify algorithmic problems and change them for a better ones, I can find allocation issues and use buffers/pools".

But lower level things like "I know which branch mispredict kills me" or "I know which access patterns results in page faults" are out of my reach. I mean, before asking the question and getting answers like yours.

So thanks for that!
