There is no filesystem layer involved after swapon.

How do you avoid that when you're swapping to a swapfile?

the file's blocks are mapped on swapon and after that the kernel writes
directly to these blocks. The only performance penalty you'll see is if
the file is heavily fragmented.

That's also the reason why sparse swapfiles with holes won't work.
