The scalability parameters for a single-server deployment are as follows:
A single-server setup is ideal for small setups of 500 to 1000 users.
Clients must have a dedicated network interface card (NIC) of 100 Mbps capacity.
Web-based access must be low, and thick client access must be moderate with up to 500 active connections.
Data transfer (synchronization of user data) rate must be 10 MB per hour per client.
The synchronization interval must be 10 minutes.
