Should I stick the rule of around 15% of mem then? I haven't found any
information on why you should use certain settings at all. I read
somewhere on the postgres site about using as much memory as possible,
but leave a little room for other processes. Whould that be an ok
theory? I'd kinda like to know why I should or shouldn't do something
like this.
