Yeah, containers or VM's up the count indeed, but still. 2 Parallels (test version for m1) VMs running server ubuntu, 1 with 2 ssh connections, for X and tunnelling, running emacs into my desktop, running a web server with repl and environment, other running Postgresql. Safari with 8 tabs open, 4 terminal windows, Xquartz, tells me the biggest memory footprint is the vm with emacs/server/repl, at 3.9GB followed by the other VM at 2.8GB, but the overall used mem says 6GB used(?). From the tabs Gmail was pointing to +1GB - a browser email client consuming +1/3 of the memory a VM running an OS plus a database. I sometimes have another VM, another 2 ssh conns, more tabs open including youtube and never noticed any slow/sluggish behaviour. I also feel like running VMs is wasteful, but it seems we are not able to create OSes with proper native tools for isolation.
