Sometime the swap memory hit 100% and the running script (PHP) is considerably slower. I'd like to ask in which scenario it is okay to run the command swapoff -a ; swapon -a to clear up the swap memory so that the running script is not affected, and in which scenario is it affected?

`swapon/swapoff` = root access so don't do that – Aug 10 '13 at 07:12

@RC why you mentioned about the root access? I'm running the application in my personal computer so there is no security concern. – aye Aug 10 '13 at 07:18
