 Posted: Sat Jul 13, 2002 12:13 am Post subject: Memory issue? |
 |
|
OK heres the issue. I have Gentoo 1.2 running on an XP 2000+ w, 768 megs of ram, 333 Megs swap, Nvidia drivers (gf4) OSS pro and I mainly use Fluxbox in X.
The thing I have noticed is that after running some apps.. Mozilla, Xmms, Realplayer, Sylphead, Win4Lin (occasionally), etc.. The memory section of my top output looks something like this:
| Code: |
Mem: 775008K av, 634992K used, 140016K free, 0K shrd, 35024K buff
Swap: 345388K av, 0K used, 345388K free 458808K cached
|
The memory usage is pretty heavy, although in itself not a real problem. Whats confusing is that looking through top, the running processes do not add up, and if I shutdown all running programs, the memory in use does not decrease.
So after an hour of having only fluxbox and an xterm open I appear to be still using over 600 megs of memory. Any ideas on how I can account for the used memory? Also is there a way to "flush" the memory somehow?

That's your system's cache of block devices. Don't worry about it; use "free" to check memory usage.

What you are seeing is automatic disk caching. When and if you have a more urgent need for the memory, the disk cache will give it up. In short - don't worry about it. Your system is behaving normally and should feel as responsive as ever.

Hey thanks guys  definately did not notice any performance issues, so that makes perfect sense. Oh and here's 'free' output:
| Code: |
bash-2.05a$ free
total used free shared buffers cached
Mem: 775008 633304 141704 0 35192 459316
-/+ buffers/cache: 138796 636212
Swap: 345388 0 345388
bash-2.05a$
