In Snow Leopard, Flash was a very slow, laggy experience. Scrolling in a website with Flash loaded resulted in heavy lag or Safari freezing. However, now in Lion, Flash is incredibly fast!

There is zero lag while scrolling in a Flash heavy webpage, and Youtube videos load instantly. I'm not exaggerating, they load as soon as the page itself loads, sometimes before the other web elements load. Impressive.

I am using Flash 10.3 Beta for 10.7.
 
I see no difference. I'm guessing the fresh Lion install/overlay merely juiced up some things that were sluggish in snow leopard for you.
 
I clean installed SL as well. No, there's definitely a huge difference in Lion.
 
I noticed that Youtube videos shows "accelerated video rendering, accelerated video decoding" now instead of "accelerated video rendering, software video decoding" in Lion
