Summary: Investigate HashMap.Node[] allocations from GridCacheMvccManager$3 Key: IGNITE-2579 URL: https://issues.apache.org/jira/browse/IGNITE-2579 Project: Ignite Issue Type: Task Components: cache Affects Versions: 1.5.0.final Reporter: Vladimir Ozerov Fix For: 1.6 *Problem* See GridCacheMvccManager.addFuture() method. We create a weird HashSet there with internal table size == 5. Can we have something more efficient here? *Proposed solution* Need to run single get-put benchmarks and check usual size of this collection. If it is often equal to 1, then instead of allocating the whole collection, we'd better to have a singleton first and expand to collection if there are more elements. Please pay attention that collection usually used as monitor in some synchronized blocks. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
