             Summary: Clustering performance regression in scenarios with ASYNC cache used
                 Key: WFLY-5811
                 URL: https://issues.jboss.org/browse/WFLY-5811
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
            Reporter: Michal Vinkler
            Assignee: Paul Ferraro


Our clustering write-heavy stress tests show a performance drop of 7.0.0.ER2 bits compared to 6.4.0 bits, when using ASYNC cache.

Compare these results:
