A post over in the cf-talk list mentioned that using CreateObject was a lot slower than native datatypes in Coldfusion, well of course it is I thought, but I wanted to see HOW slow they compare, and what the difference would be between them.

So to this aid I did a script that looped, creating objects and timing it, in steps of 50 up to 2000 objects. The code to measure this is as follows:

I added some timing info after each iteration and was adding the objects (a struct and a simple Person component) to a log file.

So you dont think that the Person component is very heavy, I did the barest component possible, you might even say its Duck-like!

The results for the component are pretty uniform, but what surprised me was how little speed it takes to create structures. Obviously this is the case, since they are basically a HashMap and in ColdFusion a very long running primitive (i.e. been around a while and optimised)

These results of course are of course unfair, you wouldnt create 2000 odd objects, you might create 5-10 of them as services and keep them cached, but what about beans?

Here is the chart of the results:
