Although this is done via C code (FFI and InterpreterPlugins) this is 
still quite slow. From first testing I'd go for 20 Sessions max per CPU 
(P4 2 Ghz). So that's the bottleneck. Hence the idea to put the DB on a 
shared NAS to keep as much CPU Power on the frontend as possible.

Now that's very interesting. Does GS allow one to seperate into an DB 
backend and DB frontend? I mean having all the data shared in one DB and 
having the GS frontends doing the Seaside and local/temp storage stuff?
