Just on a few points:

- Using all available memory for buffer cache is a good thing, as long as the OS can immediately drop it if there are more urgent uses for the memory.

- I haven't used iTerm very much, but and because Terminal has always seemed snappier. I'm surprised you had the opposite experience.



Does he mean to include buffers? On linux, the term "resident memory" refers to memory that is explicitly not buffer cache. Or does OSX use this term differently?

One day, we may be able to use the same RAM terms across all major OSs.
