Bundler using direct memory as buffer ------------------------------------- Key: JGRP-2241 URL: https://issues.jboss.org/browse/JGRP-2241 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 4.0.11 The current bundler impls use a byte[] array in an output stream as buffer into which messages are written. If we instead used a direct byte buffer (off-heap), the JDK would not create an additional copy but simply pass the contents to the corresponding socket. This would reduce the memory allocation rate. Direct buffers can also be used on the receiver side, investigate.
