I knew it… I need (at least) another 128 MB. It used to be easy: app won’t launch: add memory (or lower memory allocation manually). Now with OS X and that fancy « modern memory management », you can launch all the apps you want until the machine gets so slow that you tune out of the UI and get hypnotized by sound of your HD trashing away.

So you need a program to help you figure out when you system is cheating and paging out your memory from RAM to hard drive (did I get the technical terms correctly here?) so you can go to your admin and say « see: I told you I needed more RAM ». Unless you have a cool admin who can read the « top » output months ago and say  » yeah, you need more RAM like I need more budget ».

This is a pretty interesting program. Do I Need More Memory, a utility that can help you to determine how much RAM you really need installed in your Mac (based on pageouts), according to your average use…
