Client Load Statistics

[Jeff Casimir]

Hey all,

Has anyone done comprehensive load statistics on an Edubuntu setup using 
thin clients?  Some of the figures I am wondering about (obviously all 
approximate):

- How much data must a client transfer from the server from "power on" 
to "ready for login" (total kb)
- What is typical transfer rate between the client and server during the 
bootup of a single machine on an otherwise quiet 100baseT network? (kb/s)
- When a client is logged into just the desktop, how much server CPU 
power are they using? (%, given clockspeed)
- When a client is logged into just the desktop, how much bandwidth does 
the session use? (kb/s)
- When a client has a "typical session" running (say one instance of 
Writer, one of Firefox with 3 tabs open, and Eclipse) how are CPU power 
consumed (%, given clockspeed) and bandwidth (kb/s) affected?

I am trying to spec out the hardware we would need to run Ubuntu in our 
lab, and these statistics would really help.

Thanks for your time,
