HP Netserver & Microsoft Terminal Server 4.0

Hewlett-Packard Company 7
Memory
As with processors, configuring the server with insufficient memory will
seriously impact performance. Since memory requirements will vary, it is
extremely important to accurately size your server configuration using the
targeted application environment.
For Terminal Server, Microsoft requires 32MB of RAM, plus an additional 4 to
8MB RAM for each user to support running the user's applications on the
server (Microsoft Window NT Server, Terminal Server Administrator's Guide).
Memory utilization during our benchmark test averaged between 5 and 9MB
per user.
Network
As with processor and memory utilization, network utilization will vary
depending on user activity. As a general rule of thumb, Microsoft recommends
2 - 6Kbps per user (Microsoft Terminal Server Capacity Planning, White
Paper).
Network activity during our benchmark test averaged between 2 and 5Kbps per
user.
