This is a FAQ. See the FreeBSD FAQ list, section 12, question 12.1:

Q.
Why does FreeBSD consume far more swap space than Linux?

A.
It doesn't. You might mean ``why does my swap seem full?''. If that is what
you really meant, it's because putting stuff in swap rather than discarding it
makes it faster to recover than if the pager had to go through the file system
to pull in clean (unmodified) blocks from an executable.

The actual amount of dirty pages that you can have in core at once is not
reduced; the clean pages are displaced as necessary.
