Hello,
I noticed that my SWAP partition is used as soon as possible. I'm compiling a few things and my SWAP partition (512MB) is 45% full already with only 1.45GB/4.00GB of RAM used!

I already checked my swappiness and it is set to 10. What can I do?

What are you compiling, are you using tmpfs for portage tmpdir, etc.?
Too many unanswered questions here to explain why it's exhibiting the behavior.

And swap usage is not necessarily bad. If you never used swap, why bother having it?

Exactly. I'm putting portage dir in RAM every time...

A 4GB machine is not enough to run tmpdir in tmpfs for some packages, at least that's what I've found. Building one of the big packages will cause the machine to swap as it will run out of RAM during compile.

Note that tmpfs's content looks like disk buffers to `free` etc, so you have 1.4G used + the used space of tmpfs. You can check it by droping all caches by `echo 3 > /proc/sys/vm/drop_caches` and then see `free -m`. Note that after droping cache your system will be extreme slow for few moments.
