Coz mine ain't... On reboot, [Mem: free] and [-/+ buffers/cache: free] will both be large. As apps claim memory, both will fall. As apps access files and more data becomes cached, [Mem: free] falls. If the apps don't do much disk I/O, then it wont reach near zero. If and when it reaches near zero, it will remain that way until reboot. -- The optimist believes that he lives in the best of all possible worlds. As does the pessimist.
