OS X Applications Memory Usage

Published by under General

I expect OS’s and applications to keep running for days on end. I don’t like to close and relaunch apps as I expect them to be available. Unfortunately that comes at a price of ‘lost’ RAM. Recently, I’d been getting a lot of spinning pizzas (delays) when switching between programs and when using a program. So I checked into memory usage.

The following examples have the same page or files open and ‘rendered’ before and after relaunch.

Firefox: 750MB before 140MB after relaunch
MoneyDance: 140MB before 70MB after relaunch

Pretty dramatic differences.
