On what operating system and with how many tabs open if I might ask? With 6 tabs open (5 html files, 1 css file) and two extensions installed I get ~230 MB on Windows.
Thanks. Is unix (maybe specifically MacOS) just that more efficient, or doesn't it count multiple processes?
It's not, OP didn't count the other processes in (they are listed seperatly in Activity Monitor). VSCode needs roughly the same amount of RAM on macOS.
