I'm curious to know if "no discernible performance gain" is your own "feeling" or if you've actually done some testing. Don't castigate someone for doing something you're doing too.Here’s some data: my iPad shows no discernible performance gain compared to last week. I’ve had apps crash and I’ve had my iPad restart itself whilst watching a video, which hadn’t happened before.
People saying things are “feelings”. Feelings aren’t concrete data.
