Great paper on performance and hardware

About 6 months back, a user on Slack posted a great paper on coding optimization. It was very long and went into detail on all relevant aspects of how RAM and CPUs work. Can anyone remember the name of it?

Already answered on Slack, but this paper is too good to be eaten by the memory hole of Slack!


Well then, let me ask again:
Is it this one?

That paper was highlighted on one of our Slack channels. I missed the SO reference though.
