Note that changing it from 4 to 3 or even 2 is unlikely to really change much.
Many of the plans people complain about turn out to have critical points
closer to 1.2 or 1.1.
The only reason things work out better with such low values is because people
have data sets that fit more or less entirely in RAM. So values close to 1 or
even equal to 1 actually represent the reality.
The "this day and age" argument isn't very convincing. Hard drive capacity
growth has far outstripped hard drive seek time and bandwidth improvements.
Random access has more penalty than ever.
