Under Better Metrics the author discusses ways of drilling down to find the source of a high load average. I feel like this section should mention `atop`, which is imo a really underrated single-pane-of-glass view into everything your system is doing, now and historically. If you haven't tried `atop`, give it a go. This historical analysis in this article though is great, because while Load Average has been an oft discussed and we'll understood topic for a long time, the decisions that got us there are not.
