I believe that Fidelity (60,000+ users) has a very large enterprise Jetspeed portal with a lot (tens of thousands) of simultaneous users.

I do not know many of the details but I believe that they use clusters of servers with a single back-end database supporting 2 front-end Jetspeed servers.

Jetspeed and portals in general are intrinsically scaleable in many ways.
When you add in web services, clustered databases and the other tools that the portlets can use, you do have a lot of ways to boost performance in large scale deployments.

Sorry that I do not have many details.

We have an LMS portal with 9000+ registered users but do not have a huge number of simultaneous users.
Performance is excellent on a very cheap server.
We use MySQL running on the same server. We use a lot of webservices all running in the same Tomcat.

I hope that this helps a bit.
