[Glass] IdentityKeyValueDictionary vs IdentityDictionary?

Hi guys,

I was measuring performance of different dictionary classes for a given
scenario and I still cannot understand the difference
between IdentityDictionary and IdentityKeyValueDictionary.

For this particular case (where I was measure #at:put:) the later was much
faster. Is that always the case? Because I normally use IdentityDictionary
everywhere for identity based dictionaries.

Thanks in advance,
