[ https://issues.jboss.org/browse/ISPN-4842?page=com.atlassian.jira.plugin.... ] Dan Berindei commented on ISPN-4842: ------------------------------------ Takayoshi, the JGroups channel is already shared. There are probably some per-cache threads that could be merged, like the TXCleanupService thread that you already issued a PR for, however most threads should be shared. Sharing the consistent hash would require all those caches to be symmetric - i.e. if cache {{c}} is running on one node, it must also run on all the other nodes in the cluster. We are considering allowing only symmetric caches for 8.0 (adding support for multiple cache managers on FORKed JChannels instead), which should allow sharing the consistent hash. However, 8.0 is quite far away, so I would focus on reducing cost of computing the consistent hash (e.g. [TopologyAware]SyncConsistentHash results may be cached) and the merging per-cache threads into global threads. Please create separate issues for other per-cache threads that you've found. -- This message was sent by Atlassian JIRA (v6.3.1#6329)
