At least database_cashe_buffers*database_page_size for Super should
be multiplied on amount_of_users for Classic. Note each running server
process consume resources itself. Last depends on complexity and
amount of Stored Procedure usage and transactions lifetime.
BTW, my observations on Super (very limited, I'm Classic fan) in
general shows Super is more quick serving single connection but
Classic have much better load ability. When Super looks as entirely
'frozen' by some heavy query and practically stops serving other
connections, Classic slowed, but moves. And this is particularly
noticeable on multiprocessor machines. I have'nt HT machines so can't
surely speak about this.
