Hi everyone, I'm trying to determine the number of servers (Win2KAS/IIS5 so we can use clusters and load balancing) needed to implement a web application that will serve more or less 4000 clients (total). The aplication will need database access all the time and use ASP. How many users a single server can handle? I need some type of documentation, performance charts, etc. to support the decisions so if somebody knows where I can get this info many many thanks. Please don't answer telling me that Apache is better, the organization already has MS licenses, so it is useless to discuss that now. Thanks.
