Resolution: Fixed
> [proton-j] performance improvements in sasl transport wrapper
> -------------------------------------------------------------
>
> Key: PROTON-1774
> URL: https://issues.apache.org/jira/browse/PROTON-1774
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-j
> Affects Versions: proton-j-0.26.0
> Reporter: Timothy Bish
> Assignee: Timothy Bish
> Priority: Minor
> Fix For: proton-j-0.27.0
>
>
> The SaslImpl class adds a TransportWrapper that deals with processing the
> iincoming and outgoing sasl exchange work. When complete the wrapper leaves
> in place an implementation that must check on each new bit of work through
> the transport if it is still in Sasl mode and hand off to the next wrapper
> accordingly when not in Sasl. This checking can lead to a small loss in
> performance. Instead a wrapper that delegates to a swappable next instance
> can be switched once sasl is complete such that no checking is required after
> the sasl exchange.
> As a side affect of this change the input and output buffers allocated to
> handle sasl bytes in the exchange can be moved to the delegate
> TransportWrapper that will be dropped after the exchange and that small bit
> of memory can be freed by a future GC.
