RE: Website Slow then falls over
Thanks for getting back to me. The function of the apps on the server is a very complicated shopping system. It allows buyers for a large department stores around the world to come to the site and buy the products that will be seen on the shelves next season. There is a lot of data and very large queries, Stored Proc’s and DTS packages. The reason there is such a large amount of data is imagine if you order a t-shirt it comes in different colours and different sizes, or in other words if you have a t-shirt you could have 10 different sizes in 20 different colours – so the amount of data quickly mounts up. There is not that many users on the system, say 150ish but when they come to the site they use it very intensely. BTW I should have made my self a little clearer about how the web and DB server are connected they got a cross over cable going between the two. Do you think that running each of the sites in its own memory space (Application Protection) would help – does this load the ActiveX into its own space as well?
