"top" command memory question
Hi,
I run the command "top" and was wondering why so much memory is used. Following is a snapshot :
---------------------------------------------------
11:43am up 4 days, 1:29, 4 users, load average: 0.00, 0.00, 0.05
59 processes: 58 sleeping, 1 running, 0 zombie, 0 stopped
CPU0 states: 0.0% user, 0.0% system, 0.0% nice, 100.0% idle
CPU1 states: 0.0% user, 0.0% system, 0.0% nice, 100.0% idle
Mem: 2064172K av, 2048696K used, 15476K free, 0K shrd, 362856K buff
Swap: 2040244K av, 0K used, 2040244K free 1530488K cached
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
32408 gdm 15 0 17084 16M 6100 S 0.0 0.8 0:01 gdmgreeter
957 root 5 -10 137M 9980 2556 S < 0.0 0.4 24:10 X
-----------------------------------------------------
I've used the "M" option to sort the processes in order of memory usage. My Question is : why is (2064172K av, 2048696K used)? What could account for this large memory usage?
Thanks for any comments!
YS.
