Pro Android Apps Performance Optimization

Multicore

Recently, a number of Android devices came out based on multicore architecture. For example, the Samsung Galaxy Tab 10.1 and Motorola Xoom tablets both use a dual-core processor (Cortex A9 cores). A multicore processor, unlike a single-core processor, can execute multiple threads simultaneously. That being said, it is easy to see how this could improve performance as a dual-core processor can theoretically do twice as much as a single-core one (everything else being equal, for example, clock frequency). Although optimizing for multiple cores is not as easy as it sounds, and some caveats exist, your application can definitely leverage the additional power that today's multicore processors bring. Devices with dual-core CPUs include:
