Oh, and one more thing, we also started using the new UUID namespace
configuration and security rules in 2.42.0. But I guess that should not be a
problem performance wise(?). Most of our connections use temporary UUID queues
to reply to.

Subject: RE: Performance impact of connection router
I didn't at the moment, but I will try to change configuration on our
production system during next maintenance window to see how it affects CPU
utilization.
The reason I'm asking is that I started to investigate why one of our clusters
has a considerable CPU usage, even though the throughput load (message count
and size) is not that big at all. It is either:
a) a connection router configuration we recently introduced, or
b) something changed on the application side, maybe how developers close and
open connections, or something like that.

The performance impact is hard to judge, but I wouldn't expect it to be much as
it really just adds one invocation of java.util.regex.Matcher#matches for every
connection.
Have you conducted performance tests with and without the router? If so, what
did you find?
