This was discussed before. Collections are implemented as linked list, and 
when you use an Index, it has to walk from the start each time you refer to 
an item by its Index. If you use a Key, it's faster because it's using 
something like a sorted hash table to find the information, unless the 
Collection being indexed contains very small number of items, in which case 
it doesn't take much time to walk through it all.
