Here is the memory usage on my laptop as reported by top:
Mem: 1036484k total, 456952k used, 579532k free, 396k buffers
Swap: 0k total, 0k used, 0k free, 184456k cached
On my 1 GB laptop, I am using 450 MB of memory. However, about 180 MB
are being used by the system (file) cache, which is easily reclaimable
in case of a memory crunch. If you really want to know how much you
are using, you need to take the amounts used by the buffers and the
cache and subtract them from the total used value. I'm sure that's
what System Monitor is reporting.
A better way to see memory usage from the command prompt is "free."
This is the output I get:
$ free -m
total used free shared buffers cached
Mem: 1012 447 564 0 0 180
-/+ buffers/cache: 266 745
Swap: 0 0 0
Here free reports both the total usage and the usage without buffers and
cache.
