Not only that, but (in my experience as a Google engineer), factors relating to the location of data (distribution and disk vs ram, etc.) often greatly outway algorithmic performance. Constant factors often dominate variable factors.

Exactamundo! Cache/memory/disk locality dominates almost all other factors[1] unless you're doing something very special. (Speaking as a non-Google person who also likes to think that he knows what he's talking about.)

[1] Well, it's really the amazing amount of throughput that modern architectures can achieve. Latency hasn't improved quite as much given the inescapable limitation of the speed of light.
