Why are Flash applications so sluggish?

My flash player in Ubuntu 11.04 really sucks. When watching just about any youtube video, it will play ok for about a minute or less but then starts to jerk up a bit and slow down or freeze completely. Other times the video is black from the start but you can still hear sound playing, and a page refresh doesn't fix that. Full screen is out of the question.
The mouseover text in the xkcd joke leads me to believe some people have solved the same problem, and it must be a common problem. So what are some possible solutions I could try?
Currently I have to watch youtube in a windows virtual machine, which makes me sad.
- flash version: 11,0,1,129
- chromium version: 12.0.742.112 (90304)
- firefox: 7.0.1
- pci-e video NVIDIA UNIX x86_64 Kernel Module 270.41.06 (8800GT?)
