It's not exactly set yet, but I suppose it will be something like a single Pentium 4 > 1GHz > 512MB RAM and > 50Gb HD running mod_perl under FreeBSD...
Also, under the hybrid scenario (temporary information -> shared memory & persistent information -> file IO) I don't think the temporary information in memory will be helpful after a server crash - everyone will time-out on the client side and have to restart anyway. Lets hope we dont crash often (are you listening FreeBSD?). Does this change your opinion on shared vs. DB? Thanks for the CGI::Application tip, I will check it out. -Dev
