Re: fedora OS high memory usage

"1962316k is actually occupied by my active"
How do you calculate that 1962316k is being occupied by your active processes?

Type this:

free

Look at the second line of output data.

For example, this is what I have on this machine right now:

$ free
total used free shared buffers cached
Mem: 2057836 1958356 99480 0 77972 1437864
-/+ buffers/cache: 442520 1615316
Swap: 2031608 344 2031264

I am using 442520k of memory, but 1962316k is actually occupied by my active
processes, plus what amounts to a cache of what I have been doing recently just
in case I might want to do it again soon.

Linux uses all available ram for that sort of a cache unless it is otherwise
required for something else whereupon it is immediately released and given to
the process that asked for it.
