What are the pros/cons of using the JIT (Just-in-Time) compiler on an older phone? On an older phone originally designed to run Android 1.5 or 1.6, what are the pros and cons of using a newer Android feature like the JIT compiler?
JIT typically causes an app to use more RAM due to the JIT cache, although Android's JIT was specifically designed so the additional memory usage was minimal (compared to a typical Java JIT). On phones that are already very RAM-starved to begin with, JIT may result in a decrease in performance.
