I have a friend who says: "when you invent more efficient lightbulbs, people do not consume less energy, they just get more light" Every time we did a milestone performance improvement in our infrastructure, e.g. search used to take few seconds, we reduced it to few milliseconds. One year later our colleagues were doing machinegun-like queries and the search was back to take 1 second, and it is just a matter of time to go back to few seconds. One thing that helped a lot was hard limits, e.g. InternetExplorer9 having hard cap on css size was literally the only thing that forced people not to push megabytes of css. I wish Chrome does something similar, like 'you cant have more than 500kb of js code evaluated per page' or 'no more than 200kb css', it will do miracles in just one year, and I am willing to bet that we will have the same features we would without the limit. EDIT: I did not mean to undervalue Chrome's 49% improvement in one year, which is just extraordinary work!
