    I am perfectly aware that no technology is a silver bullet in all
circumstances, and that you have to benchmark a particular technology
in a particular case to see its effect.

    But in my original question (although I've not clearly stated so)
I was curios what is the impact of HiPE in general, meaning what is
the experience different people had with HiPE?

    More exactly what are the use-cases which are likely to benefit
from HiPE? I would guess that in a CPU bound application HiPE would do
better than without, but what about network I/O bound applications, or
applications that deal mainly with strings (represented as lists), or
applications that deal mostly with binary matching?

    Thanks,
    Ciprian.
