That fits in level 3 cache these days:

Yes, but if you want to do something else with your computer, you'd have to swap it out to proper RAM.

You mean like how it normally works? Of course it will be swapped out - into the GBytes of memory you oomputer is equipped with.

Yes, that was very funny - about 20 years ago.

On my current machine (OSX w 16 GByte RAM), Emacs built with Homebrow as native GUI application (HEAD, lots of bells and extras enabled) with 10+ buffers Emacs consumes 127 MBytes. In comparison, Finder consumes 300+ MByte, Firefox 2+ GBytes and Slack(!) 500+ MBytes. And the Activity Monitor utility supplied by Apple I used to check these numbers uses 130 MBytes.

Yes, Emacs consumes 8 MBytes and more. But Moore's law has really fixed that problem. And in comparison with a lot of other SW, Emacs is not the SW application I would accuse for being bloated, quite the opposite in fact.

Slack uses so much memory because it's carrying around the baggage of its own webkit session. It's little more than a web browser that just connects up with slack, and thus has all of the bloat and ugliness of javascript.

To be honest, I very rarely seen 8mb or more back then, when I ran Emacs on a VAXstation with 64mb of ram. Usually it was much less, but, OTOH, org mode did not exist.

Yeah, it's a problem on my i386 IBM P70 which I recently upgraded to 8MB.

That's funny the modern Thinkpad flagship mobile workstation model is called P70 exactly.
