Of course, if you can actually measure it, that would be
interesting. Naive math gives you a guess for the order of
magnitude effect, but nothing beats real numbers ;)

The SYSV folks actually did have a buddy allocator a long time ago and

performance.

See chapter 12 section 7 in "Unix Internals" by Uresh Vahalia.
