Subject [jira] [Created] (OAK-3343) LIRS Cache: investigate concurrency behavior
Date Thu, 03 Sep 2015 07:16:45 GMT
Thomas Mueller created OAK-3343:
-----------------------------------

             Summary: LIRS Cache: investigate concurrency behavior
                 Key: OAK-3343
                 URL: https://issues.apache.org/jira/browse/OAK-3343
             Project: Jackrabbit Oak
          Issue Type: Bug
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller


I have a report that the LIRS cache (in combination with the persistent cache) does not perform
well when using 50 threads that concurrently access it. The Guava cache might not be affected
(as much).

I would like to investigate, with a simple test case, what is the behavior of the LIRS and
Guava cache with highly concurrent use cases, in combination with a cache loader.
