Still don't expect too much of it. It still have more server limitation  
than native binaries (noticed in practice, not a gratuitous belief),  
mainly due to automated (not application's specific needs aware) memory  
management I believe, then bad memory management again due to the lack of  
proper type definitions and representations (everything is an  
hash‑lookup‑associative table), and less importantly, due to the start up  
overhead. JIT, even with good hot‑path optimization, do solve only a tiny  
part of the efficiency issues (not to mention these languages are not well  
suited to large scale design nor to trustability, even if JavaScript is  
more predictable than PHP, Python and others).

My point of view, is to restrict it to user gesture handling, and to  
delegate all the processing to a native application written in an  
appropriate language (to implicitly name Ada).
