Indeed. It's not as though they go through any sort of "layer." The zone ID in the kernel is just a number and it's used in much the same way that a UID or GID is used. We're always comparing based on it, and the default (when there are no zones present) is just zero (also known as "the global zone"). If you see a performance difference, then I'd class that as a defect. It shouldn't be a measurable change, just as running with either UID 0 or UID 302 shouldn't be noticably different in performance. -- James Carlson, Solaris Networking <james.d.carl...@sun.com> Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
