Chrome on Android handles it just fine, though I'm not sure what specifically you're referring to (Chrome on iOS is just a wrapper around UIWebView so it doesn't really count).
Also, on iOS there is a ~300ms delay between taps and the "click" event (see for example https://github.com/ftlabs/fastclick) which is not present on non-iOS browsers. Perhaps that could explain why it appears so slow for you?
its not even a fair comparison they both use different javascript engines. I won't comment on Apple's treatment with javascript on their mobile browser.
So again. Unless Google has added something magical in recent builds of WebKit that hasn't yet made it to the iPad then it will equally be terrible.
