I have 16GB of RAM and still frequently get Mail busy messages. The RAM upgrade did help reduce iTunes busy and Safari busy messages, however.
If you're thinking of upgrading your RAM, which I generally think is a good idea, I'd recommend monitoring your RAM use with Activity Monitor app which can be found in the utilities folder. Check how much free memory you have when first loading Mac OS X, and then whenever you're running programs that seem to be running slowly, or when you have lots of apps and windows open, and then after Mac OS X has been running for a while but no apps or windows (except for the desktop and background programs) are running. If you find your system is running slowly when you have little or no free RAM, I guess that's a good indication that you could use an upgrade. If, however, you're not using your current RAM to it's full capacity, then you probably don't need to upgrade. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
