----------------------------------

             Summary: The server does too many ConcurrentHashMap lookups to get the cache
                 Key: ISPN-9579
                 URL: https://issues.jboss.org/browse/ISPN-9579
             Project: Infinispan
          Issue Type: Bug
          Components: Server
    Affects Versions: 9.4.0.CR3
            Reporter: Dan Berindei
            Assignee: Gustavo Fernandes
             Fix For: 10.0.0.Final


Got a profiler snapshot while investigating ISPN-9198, and there are a lot of map lookups just to find the cache with the right flags and make sure it's not ignored.
