             Summary: [protonj2] Use an appropriate initial allocation size for the client message encoder
                 Key: PROTON-2591
                 URL: https://issues.apache.org/jira/browse/PROTON-2591
             Project: Qpid Proton
          Issue Type: Improvement
          Components: protonj2
    Affects Versions: protonj2-1.0.0-M7
            Reporter: Timothy A. Bish
            Assignee: Timothy A. Bish
             Fix For: protonj2-1.0.0-M8


The message encoder in the client is using a default allocation API for the output buffer which results in a buffer that is almost always to small for the encoded message leading to at least one resize and copy of the bytes as they are encoded.  The client should choose a more realistic size for the initial allocation that at least allows a small message to be encoded into the output buffer without a resize.
