Collection efficient than VB Collection

Many times, we need to use the Collection structure in the program, which can easily use Key to retrieve sets of variables

It turned out that I have been using VB to bring-to-place Collection. I found that the regular expression in the reference in VBScript is recently found.

There is a COLLECTION structure: scripting.dictionary, reference ms scripting runtime, -> vbscript.dll

He provides a method of retrieving data with key, (but cannot use Index), tested

When ITEM is inserted, its efficiency is 3-4 times that of Collection.

When using Key to retrieve data, its efficiency is 7-8 times the Collection

Different from the characteristics of Collection:

The method of providing Exists can directly detect if Item exists

Allows to assign the already existing Item:

An array of key and item values

I don't know if I don't know if the efficiency of the Collection is improved. You can test it yourself.
