I have whined here before about how Safari runs like molasses on my iPad3 with IOS8. It seems to work OK on my iPhone6+, though. But no way does it come close to running as well as it does on my rMBP / Yosemite.
In looking at ways to improve Safari so that page loads don't take 15 seconds or more, I tried turning off Javascript. And, lo and behold, performance increased dramatically. Unfortunately, the things I browse to evidently rely heavily on Javascript, so I can't really do without it entirely.
That brings me to the question of why Apple doesn't do "something" to improve Javascript performance in IOS? IMHO, that would go a long way toward making the IOS8 experience on my iPad3 a lot more enjoyable. As it stands how, there have been multiple times when my iPad has imitated a frisbee because Safari's performance is so awful. I don't know the internals of Javascript well enough to point to what exactly makes it so slow, but it is rather a pig.
