IIRC, the ARC is limit to 3/4 of total memory. That is the max, it may use [much] less, depending on overall memory use. In your case, where you are allowing up to 90%, the ARC may get small if that memory is actually getting used. zfs-discuss is a good place to get info regarding ARC vs VM memory > > Regards, > Brian > > _______________________________________________ > zones-discuss mailing list > zones-discuss@opensolaris.org _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
