JMeter Java desktop application which comes in an executable jar file and can be downloaded from here. Obviously you need java runtime(JRE) to start this jar file.
open the bin folder and open ApacheJMeter.jar file from windows explorer
Right click the Test Plan and add a Thread group
Thread group configuration
- Name - Give a name to store all settings in a jmx file.
- Number of Threads - Number of concurrent users to hit the page
- Ramp-Up Period - Thread acceleration period If the number of threads used is 10 and the ramp-up period is 20 seconds,it will take 20 seconds to create those 10 threads.i.e,one new thread in every two seconds, want to create all threads in a single shot, put zero in this
- Forever - this option tells to keep sending requests to the tested application indefinitely. If disabled, JMeter will repeat the test for the number of times entered in the Loop Count box.
- Loop Count - the number of times it has to repeat the test, it is effective only if the Forever check box is unchecked
- Scheduler - want to specify the start and end time of the test, you have an option here
HTTP Request configuration
- Server Name or IP - the server name or the IP address of the machine running the application being tested.
- Port Number - the port number used by the web application
- Protocol - the protocol used, either HTTP or HTTPS.
- Method - the request method, either GET/POST/PUT or other options.
- Path - the relative path to the page you want to hit
- Follow Redirects - follows redirections sent by the Web application, if any.
- Use KeepAlive - if checked, sends the Connection = Keep-Alive request header. By default, an HTTP 1.1 browser uses Keep-Alive as the value of the Connection header. Therefore, this checkbox should be checked.
- Parameters - the list of parameters sent with this request. Use the Add and Delete buttons to add and remove parameters.
- Send a file with a request - simulate a file upload to the Web application, good to test a large file upload through POST request scenario
- Retrieve all images and Java Applets - download embedded content.
Now save the project and run the Test, you will be seeing the samples in your configured listeners, here you can find the time taken for each thread sample hit and status of the request served by Server, number of bytes transfered and start time of the samples
Now fiddle with your code to tweak the performance.
