I recently bought a 2010 MacMini (2GB). Its used for email, surfing, a telephone answering machine, and doing my spreadsheets and letters for my home based business. In the past I've always maxed out memory in the firm belief that it improves performance. Recently though I've run activity monitor from startup and displayed the memory usage as a dynamic pie chart, as a dock icon. I've noticed that the green part of the pie chart (Free memory). never drops below a quarter of the pie chart. There are page ins of about 5.6MB where the swap file is used and a total VM size of 140 GB. Would expanding the memory to 5-8GB improve its performance?
