[ https://issues.jboss.org/browse/ISPN-7802?page=com.atlassian.jira.plugin.... ] Radim Vansa updated ISPN-7802: ------------------------------ Description: 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 was:The buffering implementation of {{TcpTransport.socketInputStream}} needs to use fixed size input buffer, rather than growing as {{BufferedInputStream}} does.
