How's your memory usage in High Sierra?

[FirDerrig]

I'm not so sure that the memory usage ISN'T a problem...

Right now I have this page open in Safari, running Activity Monitor and Terminal on my Late 2014 Mac Mini 2.6 i5 and here are the stats:

Physical Memory: 8GB
Memory used: 4.09GB
Cached Files: 1.56
Swap Used: 22.8MB

Memory pressure well in the green with a green bar below the line separating the Swap used and Cached Files sections.

I don't think I should be using the SWAP at this point.

Either something is not going right with the OS in general, or there is something wrong with my Mac mini. I have performed a clean install after the upgrade from Sierra and my memory usage is always really high. This is the only Mac since my PowerPC days that I actually open Activity Monitor and Terminal before anything else.

For some reason even on my 24 GB iMac there is sometimes a small swap like that.

Memory usage is supposed to be high since there is a lot of caching.

I understand that but I had a Mac Pro 1,1 with no SWAP being used and that was used primarily for Handbrake to rip my DVDs. My wife's 2009 iMac also doesn't use the swap and has 16GB of RAM installed.

I just don't think that my machine should be using 4GB of RAM with 1 tab open in Safari(Macrumors), iTunes, AM, and Terminal. I think I just made the wrong investment with this machine.

My iMac with 40GB is showing 11.3MB swap used.

Agreed. Memory usage is not a bad thing. Memory Pressure is the thing to watch.
