Generally that's the current recommendation today. It used to be 4x RAM on
SunOS and other "early" UNIX in the 90's and as workloads became less time
sharing oriented and more OLTP and DBMS oriented the recommendations have
shifted to more RAM with less swap (imagine a database swapping). Typically
this is a good starting point and generally a sound recommendation.
