This is largely historical. There is a bug: 5081104 NCPU has been outgrown on x86 I'm not sure if there is a good reason (besides lack of resources/priority) why it hasn't been increased yet. Incidentally, these questions are better asked on 'opensolaris-code' (or opensolaris-bugs). - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
