How about the suggested online tools? They have (or at least one of them) has a free option which you can use to evaluate. The overhead of Wt itself is entirely scalable and thus you can easily extrapolate from data using a small number of users. I think you need to evaluate what in your application is not as scalable, and that is typically your database layer. So you could just as well stick to plain HTML sessions. You should look at time used for individual requests (as printed out by Wt) -- if this time grows then you have something that is not scaling, and you also know that it will limit the possible throughput for a fixed number of threads. It might be that increasing the number of threads already solves things (removing head-of-line blocking because of waiting for I/O from e.g. a database).
