How to measure Silverlight or Flash control load time with Google Analytics

I have a simple silverlight page for for finding available domain names. This problem is equaly valid for a flash control as well.

I use Google An开发者_如何转开发alytics for monitoring the traffic. I would like to find out how long it take for users to download and render the Silverlight control.

Once the java script on a page is loaded there should be a way to start a timer and then stop the timer once the Silverlight/flash control is loaded. Key points I would like to measure are:

• Time it takes to download the silverlight/flash control
• Time it takes to initialize the control

Thanks

You can start keeping track of time via JS using setInterval. When the flash app is done loading and ready to use, you can use ExternalInterface from flash to call a JS function to stop the timer and send the tracking. I'm not sure if there is a Silverlight equivalent of ExternalInterface, but i would imagine so.
