Check Tom Evans' reply, but the basic problem would be that the test tool
would be consuming the same resources that the web server needs to use.
Ideally, you would want the server on a quiescent machine, connected to a
dedicated, otherwise quiescent network, in turn connected to the testing host
or hosts.

I wouldn't worry too much about "modeling the traffic real clients would
generate", and as long as the network has enough free bandwidth to saturate
the servers, it should be fine. But what you want to avoid is directly
perturbing the webserver processes.
