Is Memory Pressure the only thing that matters?

[Elektrofone]

I'm wondering if I need to upgrade to 32gb of Ram on my next purchase coming from 16gb on a 2017 15" MacBook Pro. I have iStat running and over the past 30 days Memory Pressure has never gone over 50%. I do 2D graphic design with Sketch, Outlook, Photoshop and Teams often open at the same time, but it's not that intense a work load.

Am I good to go with 16gb or should I upgrade if I'm not hitting the memory pressure limits currently.

Memory pressure is usually a good indicator. Page outs is the critical measurement. It indicates you’re having to swap out mutable pages to gain more space. It requires both a write then a read. Immutable pages like program code only need to be read in as they haven’t been changed.

Is there a normal amount of page out? Or are any page outs a bad sign?

This is what mine have looked like over the past 24 hours recorded with iStat:

Occasional page-outs aren’t a significant problem but if it’s happening all the time then it indicates an issue.
