I often get crap when I mention most of the time execution speed is just not important.
However it is important vastly more important for google than me or you. Simply because google and a lot of other web companies are running on such tight margins.
Consider my company is paying maybe $200/mo for AWS. When we are doing half a million a month in business. Each cpu cycle for us represents a lot more revenue for us than google is making. The flip side is programmer time matters a lot more to you and me than to google.
