Sorry, I should have been more verbose. AFAIK, Open addressing can be slower with a load factor approaching 1 as compared to chaining. Also, I feel that implementation of open addressing can be more complicated as we have to deal with deletes etc. I feel we can redesign our current chaining mechanism to have skip lists instead of singly linked lists. I experimented with it sometime back and I feel that it gives a stable performance with higher loads.
