Hmm, I can't get an RSS that small even with -nw (to use the client TUI), but leaving that aside, on my box just running GNU Emacs normally I get 88MB RSS, so maybe we just need to update the acronym. ;)
I think it's nuts that the Linux machine I run DaVinci Resolve on today has considerably more RAM than the Windows NT machine I used to use Premiere for editing on 22 years ago had hard disk space.
Back then mine was the "scary" machine in the workshop with its AMD Duron 700 and a whopping 512MB of RAM... and Emacs was just about usable on it!
