I read that a swap partition may have better performance than a swap file.
If this is true, why? Any references to kernel code is welcome.

This suggests to me that I could augment my swap partition with a
swap file, should it become necessary. How do you do this? I
have only run out of swap space once (Netscape was trying to
gunzip a local file) and linux handled it gracefully enough; when
the swap space was out I was unable to start any new programs but
I could do a kill -9 on Netscape from an existing xterm. But
still it might be handy to let swap overflow into a file in such
a situation...

# dd if=/dev/zero of=/swap bs=1024 count=<size of swap in blocks>
# mkswap /swap <size of swap in blocks>
# sync
# swapon /swap
