Swap slowly increases

performance

Should I be worried that the swap is slowly getting bigger and bigger? I checked all the processes with meminfo.pl and they all swap from a few KB the small ones like nginx, to even 7MB the big ones like Java and Apache. There is no decrease in performance though, but this is just after a 5 days uptime. Is this the so called swappiness? Bellow is the munin graph I am talking about:

It just means that there's some data in your RAM which hasn't been used for a while. The kernel moves it to swap so that more RAM can be used for other purposes such as buffers & cache. As soon as the data is needed, it will be brought back into RAM. Nothing to worry about.

Thank you. I was inclined to think that. It makes sense this way.
