[ https://jira.jboss.org/browse/ISPN-766?page=com.atlassian.jira.plugin.sys... ] Galder Zamarreño commented on ISPN-766: --------------------------------------- The problem is that NamedExecutorsFactory creates a brand new instance ScheduledExecutorFactory for each started cache. So, it doesn't matter that DefaultSharedScheduledExecutorFactory is used cos the AbstractSharedExecutorFactory from which it extends stores executors as instance variables. So, effectively, 50 DefaultSharedScheduledExecutorFactory are created, which should not be the case.

[ https://jira.jboss.org/browse/ISPN-766?page=com.atlassian.jira.plugin.sys... ] Galder Zamarreño commented on ISPN-766: --------------------------------------- The solution needs to be different. Why on earth create a brand new Default(SharedScheduled)ExecutorFactory whenever each cache is started if properties for these are defined at a global level? If you could define these properties on a cache level, then it'd make sense to create a brand new one each time, as long as properties were not the same, but you can't do that, so that needs to be solved first of all.

New subject: [JBoss JIRA] Resolved: (ISPN-766) Individual eviction threads still created in spite of shared executor factory

[ https://jira.jboss.org/browse/ISPN-766?page=com.atlassian.jira.plugin.sys... ] Galder Zamarreño resolved ISPN-766. ----------------------------------- Resolution: Done Rather than having a shared executor factory, NamedExecutorFactory now holds a ref to an instance per each executor type since executor settings can only be defined at a global basis. This enables caches to share the same executor factory for things like eviction, vastly reducing the amount of threads on multi-cache environments such as Hibernate 2LC
