> This JIRA covers improvements made to the codec, especially lists and maps.
> The work is based on 
> https://github.com/rhs/qpid-proton-old/tree/codec/proton-j/src/main/java/org/apache/qpid/proton/codec2
> The above referenced code, is quite an improvement with respect to writing 
> lists, maps and strings over the existing codec.
> Simply put the writeList and writeMap methods in the old encorder is about 
> ~10 times slower than the new encorder.
> If I run with a sufficiently large set of strings, the old encorder is about 
> ~2 times slower than the new encorder.
