Apps barely making use of multicore? Maybe in your web world.<p>We would not have been able to ship the apps we&#x27;ve shipped were it not for being able to exploit shared state concurrency.<p>... and yes, I think the Facebook app is making heavy use of multicore and SIMD; multicore directly, and SIMD by way of the heavily optimized native frameworks shipped with the device.<p>I&#x27;ve previously made of NEON to get ideal performance out of critical path file decoding on lower end devices, where having those additional CPU cycles available made the difference between stuttering and smooth UI.<p>Stop trying to fit native apps into a box you&#x27;ve defined to match your web-centric experience, where low expectations are simply the norm.
