If I have a 64 bit OS with 64 GB of RAM, and I have 25 instances running on that server with many of the instances running on 1 GB RAM and a few running on 2 GB RAM, then what is my down side? Does anyone know the footprint of JAVA when it starts up? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-server/message.cfm/messageid:6939 Subscription: http://www.houseoffusion.com/groups/cf-server/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-server/unsubscribe.cfm
