Your question seems a little vague but you may want to look at this link..

http://homepages.fh-regensburg.de/~jom30197/

What you are asking for here does not really appear to make a lot of sense
- things such as IPv4 vs IPv6 are ok to compare, as these tend to be
similar things (IP Stacks) but IPsec happens at a different layer unless
you are talking about comparing IPv4 with no IPsec vs IPv4 with IPsec with
the tunnels terminating on the device you are testing and the
encapsulation happening there.

The processes then would tend to be CPU bound, not protocol stack bound so
repeating the same tests with IPv6 should produce the same differences
which show the overhead with adding IPsec encryption to the system.

You also need to ensure that you are not testing dissimilar systems, and
if the link above has truth to it, you may get slightly improved
throughput/performance using an IPv6 stack over an IPv4 one, but it is
again very subjective and the difference in values are probably negigable
in 99.9% of all environments.

(also note - RedHat Linux or another brand of linux will produce extremely
similar statistics - the one used above was SuSe but one linux is
essentually the same for these purposes.)
