> The current version of Netty has a few bugs in compression codec.
> Further there were a large number of improvements made to netty, these might benefit
us.
> For instance, while I was investigating this sometime back I realized that poolchunk
allocation algorithm used in Netty can be improved.
> When I tested this on some of our applications I saw 10% improvement in runtime. I am
just creating this task for once 4.0.21.Final of Netty will be released, which will be done
very soon. Then I will upgrade the version & make related code changes.
