ah so you've not run 25 xterms, wicd-gtk, chromium with 20 tabs open, firefox with 200+, openscad, qemu _and_ vlc all simultaneously then :) that takes up 13 out of 16gb
no that's a developer mindset. for ordinary average person usage, libreoffice, one web browser maybe 3-5 tabs if that, and vlc: yes 8gb is total overkill.
I would say that even using a qemu with a winblows xp game on it while using an emulator or waterfox/icecat might almost use 4gb of ram but yeah... 8gb is insane for a normal user.
I see my folly now that I learned the meaning behind that show memory used by cache as free via lxtask.
well that's all.
