Well, 3 is a 100Mb commitment, 10 would be about 300Mb, which is a lot
for some people. I'm more inclined to leave it where it is and remind
people to read the tuning documents.
It's been suggested in the past that we ought to document multiple sets
of parameter choices from "small test platform" to "big fast machine";
MySQL have done something of the sort for a long time.
