> 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)
