Then you misunderstood the OP. He was asking about dict resizing:
...
When there are more and more items being added to the
hashtable, it increase its buckets and copy the old items into the
new one and re-calculate the hash value of each item.
I think this will waste some time doing the increasing-copying
thing.
Taking my response out of context to begin with doesn't really change that
I answered the question he asked ;-)
