unter &#187;Zugriffs-Phase&#171; verstehe ich die Zeit, w&#228;hrend der die Queues modifiziert werden m&#252;ssen, was nur exklusiv von einem Thread gemacht werden kann (erst danach k&#246;nnte dieser mit eigentlicher Arbeit &#8222;weggehen&#8220;). Das Problem ist nun: wenn wir im R&#252;ckstau sind, dann werden alle Threads an die Head-Time geschickt. Dort <i>drehen sie dann am Rad </i>und machen dadurch alles viel langsamer
