Google is set to announce Android 2.2 at the Google I/O event this week and one of the highly anticipated features will provide a big boost for performance and battery life. Originally the Dalvik virtual machine was implemented as an interpreter, but now a JIT compiler will be used. Already benchmarks show a roughly 6x improvement in numeric performance with the new JIT. While this will make Snapdragon-powered phones like the Nexus One seem even more responsive it will have the biggest impact on lower end phones using ARM11-based chipsets. It remains to be seen how many existing models will receive upgrades to 2.2.
