             Summary: LIRS cache: improve hit rate
                 Key: OAK-4950
             Project: Jackrabbit Oak
          Issue Type: Improvement
            Reporter: Thomas Mueller

As seen in OAK-4936, the hit rate of the LIRS cache can be improved a lot if 
added entries get hot that were in the non-resident part of the cache. 

I don't currently see a disadvantage in doing that by default, but will leave 
this setting configurable (feature flag) so that it's easy to test if we 
suspect the hit rate gets worse in some other use case.
