Shawn,Are you talking about http (tcp based users) over the network ? Or Database ? Or ??????
For http, the server is affected by:-
Arrival rate (how many new connections)
Concurrent (how many open connections)
Activity (Requests per second on open connections)
These in turn will consume different resources (memory/CPU/Network Bandwidth etc). The consumption for 'Activity' will depend on the transaction type (static page, database access etc.).
Regarding Actual v Virtual, you may have seen this type of discussion:-
If I estimate a 'live' think time of 4 seconds and I am expecting 400 concurrent users, can I set the think to 1 second and run 100 'virtual users' to simulate the 400 user load.
Given that the Client driver can deliver this rate on the network, the 'Arrival rate' and the 'Activity' will aproximate the 400 user load but the 'Concurrent' will not.
Regards
Ian
