title: jmeter multiple users problem
body: <p>We are using Jmeter to test our Php application running on the Apache 2 web server.  I can load up Jmeter to use 25 or 50 threads and the load on the server does not increase, however the response time from the server does.  The more threads the slower the response time.  It seems like Jmeter or Apache is queuing the requests.  I have changed the maxclients value in apache web server configuration file, but this does not change the problem.  While Jmeter is running I can use the application and get respectable response times.  What gives?  I would expect to be able to tax my server down to 0% idle by increase the number of threads.  Can anyone help point me in the right direction?</p>
  
  <p>Update: I found that if I remove sessions from my application I am able to simulate a full load on the server.  I have tried to re-enable sessions and use an HTTP Cookie Manager for each thread, but it does not seem to make an impact.</p>
