tl;dr - If you haven’t heard of lstopo before, you’re welcome.

While watching a recent ServeTheHome video on Youtube (I really should watch that channel more, they’ve been quality for an very long time), I noticed them mention a tool I’d never heard of before called lstopo.

It was mentioned casually along wiht lscpu (which is very useful and well known) and it had an awesome graphic (kind of like the difference between htop and top) which was very useful.

Well, I of course immediately ran lstopo on my System76 Oryx Pro:

lstopo output screenshot displaying CPU cores, NUMA nodes, memory, hierarchy, etc.

This is awesome – it’s a cool little tool, and is a great learning tool to understand memory hierarchies IMO. Hopefully more people out there know about it!
