iPad 3 on iOS 7.1 beta 4

Is anyone running iOS 7.1 beta 4 on a third-generation iPad? If you are, I would really appreciate if you can answer some questions down below!

1. Lag

On 7.0.4, there are noticeable(some are intolerable) lags across the entire system. Especially when opening Safari and exiting in and out of multi-tasking. Does iOS 7.1 beta 4 feel generally smooth now? (of course, i wouldn't expect it to be as smooth as iOS 6)

2. Memory Management

I've also noticeable that the apps tend to be evicted from memory much more aggressively. Does 7.1 beta 4 retain more apps in the memory?

I know for sure that the 5-finger gesture to home screen has been smoothened out in 7.1. Thank god for that.

Thank you for anyone who has bothered to reply!
