Two minutes is not necessarily a long time for Topology Services to launch. This is a Java applet application, and it must first initialize the Java Plug-in. Once Topology Services has been launched, close it, but keep your browser open. Now relaunch Topology Services. How long does it take to come up?
I assume you mean, then, that it takes two minutes to expand a topology group? If so, how many devices are in that group? Under what application is this group defined? How many groups do you have defined under this application?
You did not say which group you were opening. However, what you're seeing could be due to the fact that you have a large number of devices in a distributed server environment. If you are opening an RME or CS group, the local server will make IPC calls back to the CS+RME server which adds more overhead.
If you are opening a local Campus Manager group, things that would affect that performance are server resources. For this size network, your server should have at least 4 GB of RAM, and Pentium 4 2.4 GHz or UltraSPARC III 1 GHz of faster CPU.
