dictionary

When using immutable dictionaries in F# , how much overhead is there when adding / removing entries?

Will it treat entire buckets as immutable and clone those and only recreate the bucket whos item has changed?

Even if that is the case, it seems like there is alot of copying that needs to be done in order to create the new dictionary(?)
