[infinispan-issues] [JBoss JIRA] (ISPN-1918) Benchmark UNICAST vs UNICAST2 vs NAKACK2 with JGroups 3.0.x

Benchmark UNICAST vs UNICAST2 vs NAKACK2 with JGroups 3.0.x ----------------------------------------------------------- Key: ISPN-1918 URL: https://issues.jboss.org/browse/ISPN-1918 Project: Infinispan Issue Type: Task Components: RPC Affects Versions: 5.1.2.FINAL Reporter: Dan Berindei Assignee: Dan Berindei Labels: jgroups_tuning Fix For: 5.1.3.CR1, 5.1.3.FINAL Recent changes seem to have brought performance a bit down, so we need to check whether this is caused by reverting to UNICAST instead of UNICAST2 (ISPN-1892). Performance has decreased most in the 2-node scenario, where we were actually sending multicasts instead of unicasts. So we need to check whether there is a performance difference between UNICAST2 and NAKACK2 as well. If we find UNICAST2 to perform better, we can proceed with ISPN-1879 on the 5.1.x branch as well as on the master branch.
