New Android Compiler in 4.4 = Much Faster Execution TImes

When you get your Nexus 5, you can drastically speed up your apps with Android's new virtual machine in 4.4. They are calling it Android Runtime (ART) and it's replacing the old Dalvik runtime.

 

Summary: Go to Settings->Developer options to change runtimes. With ART, apps may be up to twice as fast because it uses the Ahead-Of-Time (AOT) compiler rather than Just-In-Time (JIT) compiler.

It's interesting how far we've come in software. In ages past, you'd have to precompile everything because it'd be too expensive to compile on install or on run. Now, compiling on install isn't so bad. Though when you do the initial switch from Dalvik (with its ODEX files) to ART (with its AOT files) things take awhile...

I had to enable my developer options.  It wasn't visible under the Settings menu.  I wonder if this is true for all Nexus 5's, or just because I am on an AT&T SIM card.  Either way, I'm now on ART.  And ARTy loves to pARTy!!!  :lol:

You've had to enable developer options on Android since either 4.1 or 4.2.

Are you saying that premature execution is a problem for men in Texas?

 

Not surprising coming from a Cornhusker. We know that you have envy issues with the those Longhorns.

 

:P

I'm not a Cornhusker. I come from the 712, not the 402.

I'm noticing a little better battery live using ART. But it could just be placebo!

Well given that the majority of apps are not ART optimized and the framework itself is still probably buggy, I still say that ART is off to a good start thus far.

Unfortunately I have the LG G2 and we are still stuck on Android 4.2.2 so I don't have the option for ART anyways.  I'll be curious to see if LG will include the ART option in the Android 4.4 KitKat update for the G2 at some point in the future.  I would love to test it out.
