I haven't seen any devices personally, but some of the people where I work saw some at MWC and their reaction was uniformly that it was unacceptably slow. I don't know what hardware or codebase that was, of course. Certainly, the emulator's slow to the point of being only marginly usable on my home machine --- 3.2GHz Celeron D --- and sluggish but better on my work machine --- a 2.4GHz Core Duo. The emulator's speed isn't representative of very much, of course.

Sure, but there are other key areas that are pure number-crunching --- there are a lot of complaints on the -developers list right now that view inflation is really slow, for example, and that hits performance right where the user will notice it: application startup. Given that JITs these days are known technology, not particularly hard to do, and give such staggering performance improvements I'd be really surprised if one wasn't on the roadmap *somewhere*, and I'd expect it to be sooner rather than later. -- David Given [EMAIL PROTECTED] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Internals" group.
