Go figure: when I upgraded my RAM from 512 MB to 1.5 GB, Firefox doubled in RAM usage.![]()
Don't know if I'm mistaken but Mac OS is written in such a way that the more RAM you have, the more applications are let to leave (archive) files in the RAM, so that if a user requests something he already used, it has a higher probability in still being in the RAM.
its true for all OSes current in the market.
But what about inactive RAM? I once read that it's used as an archive of old data in RAM.
It's useless comparing how much RAM your browser takes as it depends on your hardware and setup.
