hi, i have this hw with mandriva and i noticed that i configured bad my webserver... it's always quite without memory... what do you think about it?

Looks perfectly normal to me. A Linux system will use all the memory, and this shows that the system is configured properly. I don't see any problems here. You can see this by the fact that swap is hardly being used at all. It's normal to see a little usage which is why you see 108 being used.

I would only start to worry if all your swap starts to get used. Then I would just simply suggest - install some more memory.

So no need to worry about it.

Some little tweaks you can do is disable unwanted tty's in /etc/inittab. Here is a sample:

1:2345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
#3:2345:respawn:/sbin/mingetty tty3
#4:2345:respawn:/sbin/mingetty tty4
#5:2345:respawn:/sbin/mingetty tty5
#6:2345:respawn:/sbin/mingetty tty6


the # at the beginning of the lines comment them out. Just be careful that you comment the right lines, and not the runlevels! As you see above I only have two tty's enabled, and thus I free up some memory. You can also stop the system from going to swap too easily by editing /etc/sysctl.conf and adding:

vm.swappiness = 10


and then execute:

sysctl -p


and check by doing:

cat /proc/sys/vm/swappiness


and it should report 10. Other than that, you need to disable services that you are not using. Take a look at:

chkconfig --list | grep :on


see what is enabled, and what you are using from this list. Then we can take a look at the rest and decide whether it is safe to disable them or not.

In case ianw wasn't completely understood, when Linux finishes using memory, it caches it instead of returning it to 'free' status, so if you look at your output of free:

free: 2580
cached: 103664

So, you actually have 2580 + 103664 kbs of free RAM or 106244 kb free, which is 66.99% free. Not too shabby for a box running apache and mysql.
