From: Scott Eade To: JMeter Users List Message-ID: In-Reply-To: Mime-version: 1.0 Content-type: text/plain; charset="US-ASCII" Content-transfer-encoding: 7bit X-Spam-Rating: daedalus.apache.org 1.6.2 0/1000/N X-Spam-Rating: daedalus.apache.org 1.6.2 0/1000/N Thanks for all the replies - very helpful. Here is a little more information about what I am proposing to do. I need to test a site with something like 7,500 sessions being initiated per hour. The sessions are going to be relatively long, say 15 minutes for 5,000 and over an hour for the remaining 2,500. The shorter sessions will have a 45 second pause between each page request and the longer running sessions a combination of 30 second and 5 minute pauses. As suggested by Michael and Olav I will keep an eye on the CPU usage of the machines running the test sessions to ensure I am not getting any adverse effects relating to the overloading of these machines. At least a second machine running a smaller number of threads to monitor the relative response time is a good idea, thanks Michael. We have decided to ignore network effects for our current testing by using machines connected to the same switch as the web server. >From the various comments received I am thinking that multiple client machines are going to be necessary. The Remote Testing documentation appears to suggest that the jmeter testing engine would be running on the application server (I assume in my case this would be the web server), but wouldn't this be using resources that should be kept available for the application? I assume remote testing can also support multiple testing engines that execute their scripts against a common application server - is this correct? How would I go about combining the results from the testing executed on multiple clients - would it be a simple matter of merging the results files? Has anyone tried this?
