Dan Berindei commented on JGRP-1985:
------------------------------------
I didn't actually see header copying in my tests, I was just thinking of {{FRAG2}}
because you mentioned fragmentation in the description. But WildFly always uses {{FORK}},
so a default of 4 should be better even without fragmentation.
Message: make initial size of headers configurable
--------------------------------------------------
Key: JGRP-1985
URL:
https://issues.jboss.org/browse/JGRP-1985
Project: JGroups
Issue Type: Enhancement
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.6.7
By default a message creates a {{Headers}} instance of 3. This is usually enough
(transport, either {{NAKACK2}} or {{UNICAST3}}, and possibly fragmentation). However, if a
message needs 4 or more headers, there's a resize which is an additional copy of 2
small arrays.
Goal: make the initial headers size configurable.
