Umm, roughly twice as many independent tasks, assuming you can saturate your 4 cores? Think compile farms, mail relays with antispam, webservers, databases with parallelisable queries, zfs with compression, VMs, etc. Simply many background processes (dormant zones and services) can require a bit of overhead in context switching (and at a few thousand processes per core this can become a fulltime job of its own); the more cores you have - the smaller hit you get per each. Even if you do not have such loads running fullthrottle all the time, it is possible that the moment you do - more cores can help reach your goals faster in wallclock time. -- Typos courtesy of K-9 Mail on my Samsung Android _______________________________________________ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss
