In the past month I am having some serious performance issues with my MacBook Pro (2008 model).
From the activity monitor, I get that the CPU usage is low (25%), disk usage is low (256 GB SSD drive, 50% free), network activity almost null.
What concerns me is system memory usage; of the 4GB RAM I have:
Free: 35 MB
Wired: 1.1 GB
Active: 1.9 GB
Inactive: 900 MB
Used: 3.99 GB
VM size: 650 GB
Swap used: 11 GB
I have nothing particularly heavy running. Could it be that, since I have not rebooted for a few months, some executables keep requiring memory slowing the system down (memory leak)?
Is it possible to recover unused but locked memory, without a reboot?
