Decrease GMS join_timeout and increase xPING num_discovery_runs --------------------------------------------------------------- Key: ISPN-10821 URL: https://issues.redhat.com/browse/ISPN-10821 Project: Infinispan Issue Type: Task Components: Configuration Affects Versions: 9.4.16.Final, 10.0.0.CR3 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 10.0.0.Final Our default JGroups configurations have a GMS {{join_timeout="5000"}}, meaning the first node to start will always wait for 5 seconds before becoming coordinator. It should be safe to use the JGroups default of 2 seconds. To make it even more safe, we could configure the discovery protocol's {{num_discovery_runs="3"}}, so that it makes multiple attempts to contact existing nodes during those 2 seconds of waiting. {{num_discovery_runs}} is only used for the initial discovery, so there's no danger of creating additional traffic while the node is up.
