Bela Ban commented on JGRP-806:
-------------------------------
Excellent !
I changed the code locally today (no commits):
#1 Use of IDs (ints) rather than strings as keys: performance was about the same, but
space overhead was bigger
#2 Use of intern() with all keys. Performance dropped to 50% !
So it seems that the Headers class is quite efficient !
Would you be able to contribute your changes to MessageStressTest to JGroups ?
Message: investigate making the overhead for headers smaller

Related to
https://jira.jboss.org/jira/browse/JGRP-805.
See whether we can make the overhead for ConcurrentHashmap in Message smaller.
Potentially reduce the number of buckets for each CCHM (default: 16, IIRC). Or replace
CCHMs altogether ?
