The chart used on Google Finance is the Annotated Time Line<https://developers.google.com/chart/interactive/docs/gallery/annotatedtimeline>. As you noticed, those charts use Flash (and we are in the process of replacing it with the Annotation Chart<https://developers.google.com/chart/interactive/docs/gallery/annotationchart>), however that's not why they're fast. The Annotated Time Line does a lot to optimize for speed, for example, not loading all the data at once, being smart about the resolution of data that they show, and so on. If you have an example of your charts being slow, perhaps we can help you speed them up. If you do not want to share your data with the rest of the list, you can email me directly, and I can help you more with that.
