Why don't we just have 3 default config files:
2GB memory
4GB memory
8GB memory
But what would go in each of those files? Once we agree on what would
be in them, why not just have a continuous knob that does that same thing?
Because we should set defaults, not optimized parameters. Workloads vary
and we can reasonably say this is what we want BY DEFAULT for something
but we can not reasonably say, "this is what will suit your needs".
Once you get above 8GB of memory you are dealing with workloads that
vary widely and will almost always need some kind of indvidual
attention. However, 8GB and below, we can set reasonable defaults that
allow a user to likely but possibly not worry about changing the conf.
