Hi Alessandra, typically the memory needs of a server are proportional to the number of clients and to the ongoing activity rates. For a small number of clients (let's say 1-100) the memory needs are quite low. I've done many many stress tests in a pIII machine with 256 megs with no problems at all. The memory becomes an important parameter when you plan thousands of clients per server.
