> The current performance of networking/io is a bit slow in Harmony implementation. Much work to be done to improve as:
> 1. use high performance native API like readv/writev instead to fill the arrays of data
> 2. simplify the native call stack to save time;
> 3. reduce unnecessary array copy in the data read/write
> 4. remove unnecessary synchronizations
> 5. remove redundant varieties
> etc.
