Of course, you can always detect searchengine bot requests and then fix things to not feed their own slow junk back to them.

I've been looking at many page previews with big empty spaces. In many cases it is Flash content but in others it's supposed to be a Google map. Previews look a lot better when you feed a simple GIF back with the same content.
