is number '3' means something or i can use any number/symbol ?
You really, really don't want to do that. Caches are
good. Caches make things
faster. Linux doesn't have to do the same disk accesses over and over. And the memory is still 'free', Linux will give up caches and buffers as readily as 'free' RAM. Any ram sitting around doing nothing is wasted, after all!
In short, don't panic, do a little research, and always find out what you're doing
before you punch in someone else's advice.
Yes, the '3' means something. Different numbers refer to different VM modes, it won't take just anything. It also goes away on reboot, so if you forget what it was before, a reboot will undo what you did.
