My point here is that linear improvements don't really improve your scaling or performance in any real sense. Linear improvements are equivalent to buying hardware (or sharding), whereas I think the kind of really nice improvement you want is say changing an exponential factor. Because thats the kind of improvement you can't compete with by buying hardware. That being said, for a large enough server farm, yes, linear improvements are totally beneficial. (And a small enough server farm.) But its important to keep in perspective that not all betters are created equal ;)
