          headlines that ignore the raw numbers. The worst numbers
            in there are far below the threshold of user perception.
          Unless these results are compounded by running in a loop, they
          are meaningless. Not immeasurable, just meaningless.

          That piece is from 1993, but the human nervous system
            hasn't changed since then.
        
      
    Back-end web servers don't have human nervous systems. Faster
    response time means that a give bit of hardware can support a much
    higher load, saving you money
