             Summary: Off Heap iteration performance improvements
                 Key: ISPN-10574
                 URL: https://issues.jboss.org/browse/ISPN-10574
             Project: Infinispan
          Issue Type: Enhancement
          Components: Off Heap
    Affects Versions: 10.0.0.CR1
            Reporter: Will Burns


When testing out some things it was found that an off heap cache with a single entry compared to an object one takes significantly longer for state transfer. Off Heap can be improved to make iteration faster and thus improve things like state transfer.

# Off Heap entries are stored using modulus for locks. This causes iteration to not access entries sequentially as well as having to acquire the same lock many times over.
# Off Heap should optimize code paths that can be short circuited (ie. don't create stream if size is 0)
