> Project: Qpid JMS

> Affects Versions: 0.24.0
> Reporter: Timothy Bish

> Fix For: 0.25.0
>
>
> The existing transfer tag cache suffers from some inefficiencies in both the
> tag generation and the management of the tag pool itself. We can reduce the
> GC overhead created by the tag cache to near zero by changing the storage
> mechanism. The tag generation can be improved by doing the tag encoding
> ourselves instead of using the Long toHexString method and then encoding it's
> bytes, this greatly improves performance and also reduces GC overhead.
