> The buffering implementation of {{TcpTransport.socketInputStream}} needs to use fixed size input buffer, rather than growing as {{BufferedInputStream}} does. Growing buffer can lead to excessive memory consumption on heap, and more importantly, by direct memory allocated in JDK classes and pooled in thread-local caches.
> EDIT: As Tristan pointed out, the {{BufferedInputStream}} does not grow in our use case, but if {{TcpTransport}} passes a big {{byte[]}} buffer, the implementation works as read through/write through. Therefore we need to chunk all calls.
