> Mobile web apps are slow because they're secure, precisely for the reason that they cannot examine or manipulate underlying system memory. By that logic, they'd better start writing OpenSSH in JavaScript, unless they want to compromise every server in the world. Oh no! Secure doesn't imply slow. Not even sandboxed implies slow. Mobile web apps are slow because their runtime has more layers of functionality and is more complex -- therefore, it requires more processing than a native application. > Manipulating memory is fundamentally a bad desktop practice incompatible with the way that JavaScript—i.e., untrusted software—is distributed. This simply isn't true. Native Android applications also can't manipulate memory; how are web applications more secure than those? And if they aren't, why are they slower?
