One minor thing:
When publishing the site you will most likely encounter problems, as the
pom is missing some configurations regarding the scm publishing.
The Pool2 pom currently uses Cp28; the current release is 32.

My question is quite simple then: will [math] add an

My experience is that the only way to get really high performance with

Can you explain more clearly exactly what you are doing? What needs
to be aggregated when? How are the threads managed?

I still think that what you need is a thread-safe copy rather than a
thread-safe mutate. Even if you force every thread to do the copy, the
aggregation still still wins on complexity/correctness/performance ideas.

Right. That is why I asked exactly how things work. If you can't
lock during aggregation, we need something different.

Correct, again depends on
The copy doesn't have to lock if you build the right data structure.
The thread leak problem can be more serious.

Well before patching a consistent solution needs to be found.
Sorry to go back to LongAdder but the idea is to add instances but not as
much as thread. Just what is needed. It means you decrease the number of
instance to aggregate so the lock time.
The queue solution sounds worse since a queue

Do you really think that more than one metric has to update (increment,
say) at precisely the same time?
