I need to get an idea for the maximum number of users that I can get to connect to an IBM mainframe using TCP/IP. I'm interested in factors that limit performance (e.g., I'm assuming that probably 50% of the host CPUs time is going to be spent just running the TCP connection for each user); I am particularly interested in any bottlenecks that would physically prevent more than a given number of users from connecting. I'm assuming that a single 3172 probably supports a finite number of concurrent TCP connections to the IBM host, but could you use multiple 3172s, or multiple gateways from some other manufacturer, that would allow you get many hundreds of concurrent connections? Today I might only need a few hundred connections. Over time this number might approach 1000 concurrently connected users, so I need a scalable architecture. Any thoughts on this are appreciated.
