Kubuntu uses too much memory. What is the cause?

many times, when i really need to put everything in RAM again (i hate
waiting for swapp->ram moving while in the middle of working), i do a:

cat /proc/swaps   (not necessary, i like to know how much is used)
sudo swapoff -a   (everything in swap moves to RAM)
sudo swapon -a
cat /proc/swaps   (make sure 0 swap is used)

i have the above 4 lines in a script called "freeswap", chmodded and put
in /usr/local/bin . and i use it very often :)
