Martin Ritchie commented on QPID-770:

Is this something we want to do now that we have an improved Topic Exchange?

>             Project: Qpid
>          Issue Type: Improvement
>          Components: Java Broker
>    Affects Versions: M2.1
>            Reporter: Martin Ritchie
> The current naive topic exchange in the java broker creates a lot of garbage for every
message. In a production system that will have very small number of changes to the subscriptions
it would be more efficient to cache the results of the routingkey lookup and so not have the
garbage over head from parsing the routingkey.
