It's the memory latency, stupid · Pivot blog
- When you see your databases CPU at 100%, what is it actually doing?
- We like to act as though CPUs run code linearly for simplicity's sake, but in truth CPUs are incredibly complex beasts; they can potentially do many instructions at once, or sometimes none at all (despite our console showing 100%).
- Because CPUs can do so many things, one CPU at 100% may be doing much less than another at 100%.
