Firefox Nightly Gets New Baseline JIT Compiler
While the great sunspider battles will be great for the future, practically does this really matter? Does it really have any impact at all for an average user, where, I suspect, the up-front costs of JIT never actually pay themselves off.<p>This isn't intended to be Luddism, and these improvements will benefit future apps, but so much is made about JavaScript performance (see the hoopla about JIT being disabled for embedded browsers on iOS), yet I seriously doubt it makes an ounce of difference in the real world, where the overwhelming majority of the performance limitations exist in the DOM.
