Andrew Munn, a former Google intern, has a great article on why Android will always be laggier than iOS.
Here’s why Android can’t render its touch UI without lagging, according to Munn. In iOS, UI rendering processes occur with dedicated threads in real-time priority, halting other processes and focusing all attention on rendering the UI. . In other words, every time you touch your finger to your iPhone’s display, the OS literally goes crazy: “Someone’s touching us! Someone’s touching us! Stop everything else you’re doing, someone’s touching us!”
