My applications suddenly slow down in operation.I TOPed it for checking out.It said :

81 processes 78 sleeping, 3 running,1 zombie,0 stopped;

CPU states:0.4% user,0.0% system,0.0% nice,...99.6% idle;

Mem 255264k av,251812 used,3452 free,0k shrd,6072k buff,209112kactv,10324k in_d,4724k in_c;

Swap 0k av,0k used,0kfree,5565k cacked.

The memory was hogged too much?
And what I should do with that?
Thanks very much.

You should add some swap space, since you have none. That way, pages that are idle can be moved out to make room.

Having no swap is really a bad idea. It is almost certain that it is causing your problems. I'd create a swap partition (or a loopback file) with size of at least 256MB.

Thanks all!How to create a swap partition post installation?By command line?

The easiest way is to create a swap file. The following instructions will create a swap file of 512MB (2x your RAM). As root:

dd if=/dev/zero of=/swap bs=1M count=512
mkswap /swap

Now, edit your /etc/fstab, and add the following line:

/swap swap swap defaults 0 0

To begin using the swap space immediately:

swapon -a

The top command will show the swap space and its usage.
