Martin Ritchie closed QPID-770.
-------------------------------
Resolution: Won't Fix
Not required as the new lookup is very quick. Performance can be gained easier
elsewhere.
> Cache results in Topic exchange from routingkey lookup.

> Key: QPID-770
> URL: https://issues.apache.org/jira/browse/QPID-770
> 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.
