I cannot say that I have any infrastructure to do this myself, but under
HP-UX at least, we have an unsupported profiling tool that should be
released "RSN" called prospect that would be able to get a profile of a
non-stripped, threaded binary.

So, if there is a pre-canned measurement "thingie/benchmary" to drive
the server, and someone can procure a binary, it would be possible to
get a profile under HP-UX at least. I can throw a couple cycles at
trying to run such a thing, but I cannot throw many at getting binaries
and benchmarks made and the like.

I should think that there are profiling tools on other platforms that
should be able to do as well. Much as I would like it to be the case, I
cannot imagine that HP is alone in this regard.
