What's in Flash 10.1? Better error handling, microphone access, GPU acceleration, better video streaming, peer to peer networking, reduced cpu hogging on busy pages (example: not activating Flash until it's visible on screen, shutting down running Flash programs) - Amit Patel

Reduced cpu hogging! I've been wondering: are flash apps such CPU hogs because they're poorly written, or does flash not provide enough types of events that everyone ends up polling for everything? - Laurence Gonsalves

Laurence, it is the former, not the latter. Biggest newbie error has to do with not cleaning up after yourself. - Jason Wehmhoener

I think it's both. I think mostly it's apps that keep polling and timers going for animation and don't turn them off when you're in another tab or whatever. But I also find that even when I have no event handlers or timers, there's still a non-zero cpu consumption, which is rather annoying. I had also read somewhere that because plugins must use the ancient Netscape plug-in API from long long ago, there are some issues that are hard to resolve properly. :( - Amit Patel

Here's a blog post that has a little bit about plugin performance: http://webkit.org/blog... - Amit Patel
