> We are noticing a performance degradation when switching to Artemis in places
> where we are sensitive on the millisecond level. We have confirmed that
> moving to ZGC and having minimal GC pause times cannot explain this spike.
> Looking at a flight recording, it does appear we are spending a lot of time
> blocked on TypedProperties getters (see screenshot). It seems like we can
> probably remove some of the locking here with a concurrent collection or be
> smarter about it with a ReadWriteLock, given that it appears we have threads
> competing for read calls.
