That way you find you need to allocate LESS resources to Online. E.g. MAX (buffers for application one) + MAX (buffers for applciation two) > MAX( buffers for applications one and two AT THE SAME TIME)... less memory used. Less contention as max cpu vps active for application one + max cpu vps active for application two can exceed the number of physical cpus resulting in more cache thrashing etc. You may have >1 app but they will almost never have their maximum workloads happening at the same time. -- David Williams Maintainer of the Informix FAQ Primary site (Beta Version) http://www.smooth1.demon.co.uk Official site http://www.iiug.org/techinfo/faq/faq_top.html I see you standin', Standin' on your own, It's such a lonely place for you, For you to be If you need a shoulder, Or if you need a friend, I'll be here standing, Until the bitter end...
