    Ich hatte die Bench auch mal gemacht (vor ein paar Tagen) und ganz ähnliche Ergebnisse erzielt.
    Der Performanceunterschied belief sich auf meinem PowerMac G4 QS auf gerade mal 0,3 Prozent (JFS natürlich langsamer).

    Seither habe ich Journaling eingeschaltet.

    die prophezeiten 20% sind es dann doch nicht.
    Ich lass es deshalb auch laufen.
