 Posted: Wed Jan 01, 2003 11:45 pm Post subject: memory loaded for nothing ! |
 |
|
My pc is running X, gnome-sessions, nautilus, kmail and xmms.
And as you can see, 497MB of my RAM is already gone, leaving me with 17MB free (out of 512MB).
I know RAM is supposed to be used, but this much for a PC which is practically doing nothing? doesnt this get classified as a bad memory management of kernel??
what can I do? is it normal? I dont think even windows does it this bad.

oh boy, your X is using 322MB. i dont think its normal.
there must be running some process that is using a lot (!!) of memory.
play around with "top" (from sys-apps/procps) a little bit. watch the fields VIRT, RES, SHR.
look at man top for what these fields mean. |

That "296044k cached" line refers to the amount of disk currently cached in memory. Subtract that, and you'll see the active processes are really only using about 200M.
Linux puts every scrap of RAM to use whenever possible. You should be thrilled that Linux is using almost 100% of your RAM, that means those DIMMs are doing something more than just sucking up power.  |

| yes linux is using the memory left from running programs as cache and frees it up if new or running programs need it more. this is a normal operation of linux memory management. |
