You should run through the USE method on the system. In particular, you should be paying attention also to the microstates of the various processes involved to determine where you're spending your time. It's very easy, for example, to have low throughput because you don't have enough CPU on either end, etc. Robert ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
