The rt hash doesn't do well at all on your data. The winner on your data
is crc32 which is very robust in all tests on all data it seems. It's
just a shame that it's so cpu-consuming compared to the other hashes.

No real diffrence between crc32 and crc32_bof, crc32_bof is slightly
more cpu-consuming but that's it.

Have you tested crc32 with initial seed as well?
crc32 + seed that's randomly generated at conntrack init would probably
work well.

Never argue with an idiot. They drag you down to their level, then beat
you with experience.
