What a day this has been at the Google I/O!
I have run around and talked to numerous extremely interesting people, including Googlers who have hinted (nothing is official until it's announced tomorrow and, of course, they could be trying to trick us) and pretty much unofficially confirmed some very interesting details about Android 2.2, also known as Froyo.
Performance
First up, I have confirmed that JIT will definitely be included. As we already broke earlier, simple benchmarks show a 450% improvement in speed over Android 2.1 Eclair, due to JIT.
But this is just the beginning. JIT can't help performance everywhere and in some situations has no effect at all, such as I/O operations or while running native code.
