Thanks for the info. I'll look into it a bit more, but based on
http://gentoo-wiki.com/FAQ_Linux_Memory_Management
"To see a better estimation of how much memory is really free for
applications to use, run the command free -m"
Laptop:
total used free shared buffers cached
Mem: 1010 282 728 0 10 119
-/+ buffers/cache: 152 857
Swap: 250 0 250
PVR backend:
total used free shared buffers cached
Mem: 487 463 23 0 75 156
-/+ buffers/cache: 231 256
Swap: 251 0 250
Fileserver:
total used free shared buffers cached
Mem: 122 103 19 0 30 43
-/+ buffers/cache: 29 93
Swap: 244 0 244
Webserver:
total used free shared buffers cached
Mem: 218 198 19 0 5 64
-/+ buffers/cache: 129 89
Swap: 494 88 405
(My pvr frontend is shut off atm, as the lamp in my HD tv blew out last
night :( )
But, the results from top and free both show similar results in the
amount of swap used, so I still doubt that Linux naturally uses much
swap space by itself.
I could easily be wrong, and would appreciate any direct references
anyone would care to give. (A google search is an awful lot to parse
when you don't know precisely what you're looking for.)
