I tried switching to ART but the whole phone became extremely slow and laggy. Did any of you guys experience this? Should I leave it for a while to sort itself out?
Also, a lot of my installed apps disappeared from the launcher? Is this normal as the apps do not support Art or should they still show up?
The first reboot after the switch from Dalvik to ART took about 10 minutes for me. It depends how many apps you have installed, as it needs to pre-compile all of them. After that I didn't notice anything being slower or missing.
In theory ART should make it faster to start applications and should help with battery life as well, as it doesn't need to compile the apps on the fly as you start them. That's the theory anyway. I had ART on on my Nexus 5 as well from the beginning and none of the apps I've used misbehaved.
