Comment 3 Alan Field 2013-09-26 18:57:47 UTC 
Updated with test results from JDG 6.2.0 ER1. Reads are 20% slower and writes are about 12% slower than in JDG 6.1 GA
Comment 4 Radim Vansa 2013-12-10 09:30:20 UTC 
The issue was fixed in JGroups 3.4.1
These configuration options are required for optimal performance:
(TCP|UDP).bundler_type="old"
UNICAST3 protocol
(UFC|MFC).max_credits="2M"
