For all CPUs in whatever processor set sendmail is running in, which by default would be the whole system. Brian> IHAC ...

I'll let someone more expert on the fair-share scheduler comment on that. Brian> Also, would pools with processor sets make this better or worse? I would suspect better, since only CPUs in that processor set would be counted. -- John http://blogs.sun.com/jbeck _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
