well, it really all depends on your skills in patching and C-coding (or
python, lua, ...)


anyhow, i would say that you should go for the abstraction
implementation, unless it is either not possible at all to do what you
want as an abstraction, OR you really need to few extra percent of CPU.

and probably one more reason: if you know that you can implement the
entire thing in C within 5 minutes and it will take 3 days to do the
patching, i would go for the eternal.

if you are unsure, chances are high that it is possible to do it both as
abstraction and external and the few extra percent won't matter.
go for the abstraction then.

hmm, the only comparable "numbers" i can think of, are performance
comparisions.
create 1000 instances of one implementation and compare it to 1000
instances of another implementation in terms of CPU consumption.
of course this only works after you have done both implementations.
