You're still confusing me. Do any JDK's run on OpenBSD? If so, how? Which?
Why? (no, skip the last one).

*shrug* Best benchmark and profile it before you start optimizing parts of
it. The biggest speed hits are taken from design decisions, IMHO. These far
outweigh (sp?) what a JIT can give you. Also, if it's raw CPU power you need
don't factor out getting a CPU upgrade instead of actually improving your
code. How many manhours does a CPU cost, and what's the speedup per
man-hour? :-)
Here we had a situation where a client demanded "absolute real-time
performance!". What he meant was that he wanted a human to be able to see a
certain action in the database when he next asked for the reports page. That
actually gives the application a few precious seconds to buffer database
accesses, allowing us to write 10-20 records at a time instead of individual
records. And to think that we were shopping around for faster databases. :)
