I have an aesthetic UI element, a reflection, that works well on the iPhone 3Gs and iPod Touches, but is too slow on the 3G and prior. How best can I detect CPU speed so I can disable this function?

I have an aesthetic UI element, a reflection, that works well on the iPhone 3Gs and iPod Touches, but is too slow on the 3G and prior. How best can I detect CPU speed so I can disable this function?
What I ended up doing was to time one iteration of my “slow” routine. If it takes more than 0.5 seconds, I decide that the CPU is too slow and I turn it off.
In order to make the UI not confusing, I add a preference to toggle that routine, and if I turn it off, and the user selects, I display a message saying that the “feature” is CPU intensive and may some aspects of the application seem sluggish, and they may wish to leave it off. If they turn it on anyway, that is their choice. I will run this by my beta testers to see if I am making it too confusing.
Next step is optimization, but so far, I have not been able to make it much faster.
