OP here, if you have any questions or tips for other similar tools you use I would love to hear!

It's not necessarily about the content, per se, but I personally had no idea what "RSS" was (I was confused for a bit about what your program had to do with it). Maybe you could have expanded the abbreviation once at the start to "resident set size" so it would aid me being able to look it up?

RSS is really common terminology for the topic (memory allocation). You couldn't Google for 'RSS memory'? I don't agree that every article should cater to a layperson who has zero domain knowledge.

The terms do get a bit tricky, with forking servers like "unicorn" that do copy-on-write memory we also have the term PSS which is a far more accurate was to calculate memory impact for such servers.

The difference between the RAM your program uses to PSS to actual memory your process can reach vs the memory your program has allocated can all make your head spin. Agree it makes sense to add a section to illustrate this.
