You can build CouchDB with HiPE enabled but unfortunately there are
stability issues that come into play. I don't believe anyone has
looked into what or why so its never been recommended to do this
across the entire code base.
OK, I think that´s a good questio for me to answer.
I will try to do this with HiPE to find out the issues
There is a --with-native-mochijson2 (or
similar) option to configure which will compile the JSON encoder with
HiPE if available. I don't know if anyone's posted comparison data or
not though.
I will test with this option, and I will benchmark with the standard
build process to view the
diferences between both:
./configure --with-native-mochijson2
and
./configure

regards,
I was reading a great post from Jack Moffit´s blog about "Speed Up Ejabberd"
and one thing that he told there is the use of the native code compiler
(HiPE) for CPU hungry modules on this way:
cd src/
erlc +native module_code.erl
Have you tested the CouchDB´s source code with HiPE?
It would be nice to have these results on any case
