But RAM is cheap. a 32GB stick is usually under $200. And 80 million customers?

And the development of such a system would cost significantly more than throwing a couple more sticks of RAM into your server, and have on-going training and maintenance costs. Yes, engineers like to create an elegant solution, but sometimes the cheap solution just makes a lot of sense. > > Anyone with experience solving this type of issue? > Many thanks! > John > > ---------------- > John Murtari – jm5...@att.com <mailto:jm5...@att.com> > Ciberspring > office: 315-944-0998 > cell: 315-430-2702 > > _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users > <https://lists.isc.org/mailman/listinfo/bind-users> to unsubscribe from this > list > > bind-users mailing list > bind-users@lists.isc.org <mailto:bind-users@lists.isc.org> > https://lists.isc.org/mailman/listinfo/bind-users > <https://lists.isc.org/mailman/listinfo/bind-users>
