What? 9MB of RAM is used...Buffers and cache are files stored in
memory. This way, commonly used files don't need to be read from the
hard drive each time.
What I don't understand is why this question is asked so
often...Iztok, I'm not picking on you: You are not alone, many many
people ask this, and it is answered over and over. ANY modern OS does
this. Even Windows 95 does file caching. If you use the System
Monitor to watch memory useage, Win95 starts up at about 35MB when
you've got 16. Win98 by itself uses MORE. If you've got more RAM,
those figures grow due to file caching.
Is this covered in the RedHat FAQ?
