There already are speed differences in iOS alone. The native Safari has a faster JavaScript engine than the sandboxed Safari instances that iOS apps use. Or so

There already are speed differences in iOS alone. The native Safari has a faster JavaScript engine than the sandboxed Safari instances that iOS apps use. Or something like that. Something about security concerns.

It's the JIT for JavaScript that's disabled. I've never seen an official statement on it but I've read that it's that the security model in iOS does not allow compiling code and then executing it, but Mobile Safari gets a unique bypass for this security. Other apps which merely embed a UIWebView are stuck with interpreted JavaScript.

  Any user process cannot allocate executable memory, hence you cannot have any JIT.
