supposedly this is why Google's Chrome iPad app feels fast yet is actually slower than Mobile Safari at JavaScript The JavaScript performance fetish has shockingly little relevance to the actual runtime performance, beyond being a loose correlation with "focus on performance". Aside from JavaScript still being relatively trivial, benchmarks focus on the same code running thousands of times, where reality often sees a given piece of code executed one or in the single digits, annihilating the JIT benefits. Safari on Windows is a horribly, horribly slow, sloggy browser, yet it has amazing JavaScript numbers.
