             Summary: Investigate removal of hashCode from memory block and rely solely on equals
                 Key: ISPN-8422
                 URL: https://issues.jboss.org/browse/ISPN-8422
             Project: Infinispan
          Issue Type: Sub-task
            Reporter: William Burns
            Assignee: William Burns
             Fix For: 9.2.0.Alpha2


We could remove the hashCode 4 bytes taking up space in the allocated memory block. Currently this is only used for eviction, maybe instead we could write a VInt that says which offset of locks to use. In majority of cases <= 64 cores this will result in saving 3 bytes per entry.
