I believe your suggestion is good to get the best from routing (that's ok
for othes and more common/important use cases): re mqtt, I am aware of some
cases that can stress the same behaviour I have implemented on the JMH
benchmark ie given a big amount of topics, concurrent adding and removing few
new ones (routing few messages) while routing on the other ones.
I can add some fake routing between add/remove but the problem is always the
same: locking and linear (double) traversal of matching bindings (see the
linked addresses behaviour) are the bottlenecks.
Improving this use case won't hurt existing ones (that's my purpose here)
and that's what this benchmark can help to detect.
Tomorrow I will let @gtully continue on this; I know he was working on
something related
