[Seaside] Server sizing - 100 concurrent users

[Edward Stow]

Avi

Thanks for the reply -- I however have just re-read my clients
requirements and the *mininum* number of concurrent users is100 so the
max could be a lot more.

So I need to assumen that the maximum number of concurrent user
sessions was 500 or even 1000.  Is their any experience with running
this number of users with Seaside and if so what specification
machine?

I point out the application is fairly simple - no database requirement
or concurrent access to data among the user sessions.
