I don’t think the conclusion need a lot of precision in the benchmark. When the suggested code from the standard library (or some tutorial) is two orders of magnitude slower, something is not right.
The author is right that we are wasting something somewhere when we are only operating at 2% of the possible speed of the hard disk.
