I always thought that only "free" would report the correct memory numbers.
Right now, "top" reports this on my FR:
Mem: 123856k total, 118412k used, 5444k free, 136k buffers
Compare that to the output of "free":
root at om-gta02:/media/card# free
total used free shared buffers cached
Mem: 123856 118272 5584 0 136 75712
-/+ buffers/cache: 42424 81432
Swap: 65528 28 65500
The line "Mem" shows memory used including caches that will be
overwritten whenever a program requires more memory.
The line "-/+ buffers/cache" supposedly shows the real memory usage,
currently about 42M. If that were to reach 128M, we would be in real
I'm going to turn the swap off again...
