Gentoo ist eine Source Based Distribution, dies bedeutet, dass bei der Installation einer Software kein fertiges Paket heruntergeladen wird, sondern nur Source Code, dieser wird dann lokal kompiliert. Mit der Zeit wechselt man vielleicht die Hardware, Software wird erweitert, man wechselt den Kompiler. Dann ist es hilfreich zu vergleichen, wie lange das Kompilieren der einzelnen Versionen gedauert hat, dazu gibt es zwei Möglichkeiten:
