In my POV, the admin show know what he's doing. This includes be aware of the limitations of the software he uses. A 50% performances loss just "in case" is not accetpable. Or at last last there should be a way for the admin to revert to an acceptable configuration, performance wise, without hacking and rebuilding from sources. -- Manuel Bouyer <bouyer@xxxxxxxxxxxxxxx> NetBSD: 26 ans d'experience feront toujours la difference -- _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
