I ran tests on iPhone and Android 2.0 SDK with Showcase and I didn't see any significant different in startup times over wifi (3g/3dge may be a different story), so the latency improvement really only shows up in degenerate test cases where all functions are polymorphic, small and/or empty, so that parsing function decl headers becomes dominant. However, a 2-6% size reduction is nothing to sniff at, so I'd still say it's worth it.
