Bela Ban updated JGRP-725:
--------------------------
Summary: FRAG: option to discard output stream, so we don't keep large buffers
around (was: FRAG2: optionally use Message.size() rather than Message.length() to compute
message size)
Description:
When we send many small 1K messages, the size of the ByteArrayOutputStream's
underlying byte buffer will be 1K (before fragmentation). When we then send a 10MB
message, the size is 10MB. When we subsequently only send 1K messages, the 10MB are still
kept around.
SOLUTION: add option to create a new BAOS every time a message is fragmented.
was:
FRAG2 by default uses Message.length() to compute the size of a message, to determine
whether the message need to be fragmented or not. If we have many headers, this might
*not* fragment the message, but when marshalled, the message might be too large for UDP to
send it.
SOLUTION: add a use_real_size property which uses Message.size() instead of
Message.length(), and ignores 'overhead'.
