Hello,  official numbers would also be interesting to me. I can tell you that we do have some larger infrastructures running on several engine hosts, one of them for example has 3 datacenters, 7 cluster, 200 hosts. We do have noticeable performance issues on the engine host. The engine is already running on rather performant hardware including 12 cores and SSDs - but nevertheless we have load averages >20 on it and very slow response time from the engine itself. best, Dominique Taffin Systemadministrator IT Operations Platform Core Services 1&1 Internet SE | Brauerstraße 48 | 76135 Karlsruhe | Germany Phone: +49 721 91374-3912 E-Mail: dominique.taffin@1und1.de | Web: www.1und1.de Hauptsitz Montabaur, Amtsgericht Montabaur, HRB 24498 Vorstand: Christian Bigatà Joseph, Robert Hoffmann, Hans-Henning Kettler, Uwe Lamnek Aufsichtsratsvorsitzender: Michael Scheeren Member of United Internet Diese E-Mail kann vertrauliche und/oder gesetzlich geschützte Informationen enthalten.
