Hi Guys,
Just discovered what makes the iPad 3 slow.
Yesterday I installed iOs 8.4 and it started out as the biggest mistake of the century. Anyhow, after I messed around with the device, restarting, reseting, in DFU, recovered it from a backup, started a clean device +++ I discovered one thing. When I started a clean and new device it worked perfect until I did some basic and "known tricks" to save basic battery and system resources. The few times I tried to recover the unit with an old backup it also ended up as a mess.
SO... I gave it som thinking and discovered the one setting thats the connecting link was the setting "Reduced Motion" by turning this one off the unit out of resources to process the iOS 8 effects and transitions. I tried to turn this setting on (Settings>General>Accessibility>Reduce Motion), and guess what?! The unit worked like a charm! My iPad have never worked as good as it does now.
The reason? This setting starts a service called Parallax. Generally this service helps the ipad to process graphics, effects and transitions. It makes an impact on both the respons time as well as system performance. For those of you who know some basic DAW and digital studiorecording, you can see the Parallax as iOS8 answer to digital recordings ASIO driver (reduced i/o latency).
The lesson for the future is; DO NOT TURN THE "REDUCE MOTION" SETTING OFF TO SAVE BATTERY TIME.
IF YOU TURN THE "REDUCE MOTION" OFF YOUR IPAD 3 WILL BE SLOW AND UNUSABLE.
