    Hello.

    What's the difference between inactive and free memory in activity monitor? Thanks.

    Basically, inactive memory contains data that is no longer being used but stays in RAM until another application actually needs the space. Free memory actually contains no data and hasn't been used yet.

    For more information, check out Apple's Knowledge Base article Mac OS X: Reading system memory usage in Activity Monitor.

    When running OSX for a long time (example: running for more than a week without shutting down), opening and closing various applications, do you experience eventual overall system slowness? The obvious first solution seems to be to restart the computer. Can the slowness be attributed to the computer's inability to access inactive memory?
