Android to Get 100%+ speed boost with ART from Android 4.4 onwards.
English

Android 4.4 (Kitkat) comes with the option to use the upcoming Android RunTime System instead of the current Dalvik JVM to give a speed boost of approximately 100%.

 

This basically transforms Android from running in interpreted code  using a Just-in-Time compiler to compiled native code.

 

This is currently giving around a 100% performance improvement in apps, albeit with a 10% increase in app size, with higher gains expected in the final release.

 

If you have an Android phone running KitKat (4.4) you can turn it on in Developer Settings -> Select Runtime.

This feature is expected to become standard in the next version of Android (4.5) aka Android 5.0

Dalvik already uses JIT, ART uses Ahead-of-Time compilation (the reason for the performance boost)

Where did you get the 100% performance boost from? Between 10 to 50% is what most are quoting.

Its also strongly advised you don't use it at the moment, as its a work in progress and causing issues with some apps

RE: RE:

It is certainly feels faster in use but some apps (Whatsapp for instance) do not work at all.

Personally I feel the extra space the apps take is a small price to pay for an overall slicker interface.

RE: Android to Get 100%+ speed boost with ART

It's  up to 100% improvement and I think that was only on a couple but generally , you get a good improvement though it's still classed as work in progress.

 

Here a site where you can check if your apps work or not, so if all your apps work you can give it a go, as mentioned increased apps size and initial boot time while it converts everything to AOT is the downside , you can always go back if it doesn't work..

 Edit , Maybe should have said but was going out when posted earlier, Running on ART Ahead of Time facility for a couple of days now no issues but my Nexus 4 not got a lot of apps , basically phone, music player and games..

 But worth a punt ..
