Subject Re: Testing J2EE application for 1000 threads(users)
Date Tue, 06 Jun 2006 12:59:03 GMT
The Ramp-up time serves two purposes:

- allow JMeter to reach steady state
- allow remote servers to reach steady state

JMeter classes may perform some one-time init; likewise servers.

Other than that, the ramp-up is not relevant to the number of users.

It's unlikely that a single host will support 1000 users unless it is
seriously powerful.
