How to calculate the network speed. memory, CPU). of Users Calculator (Thread Calculator) Transaction per second (TPS) Calculator Pacing Calculator Think Time Calculator Required Load Generator Calculator CPS Calculator (Bandwidth Simulation Calculator) Required Test Data Calculator You can input and calculate these data in excel likes this: (Reference: http://blog.neustar.biz/web-performance/estimating-concurrent-users-based-on-past-traffic/), Reblogged this on perftexpert and commented: So you can repeat the above steps to estimate. press 'Start' Selecting the correct number of Concurrent Users is pretty easy. Server Hits per Second. Transaction Throughput vs Threads. JMeter can be used to test the performance of both static resources such as JavaScript and HTML, as well as dynamic resources, such as JSP, Servlets, and AJAX. So, if we set Jmeter up to 6GB(Xmx6144m). Apache JMeter testing tool offers following benefit in Performance Testing. It depends on how complex your test is. Hence the users which are running under a test plan; irrespective of the activities they are doing; are ‘Concurrent Users’. The concurrent connections feature allows JMeter to create a more realistic simulation. How large you can select the number of threads value on the client machine is dependend on many factors and you have to test it yourself, but since the purpose of … While I was browsing for documentation on the topic, I found a sample JMeter plan specific for Drupal on Drupal Performance Testing Suite’spage. Hi Naveen, Thanks for highlighting an interesting testing topic in a detailed, very simple, structured and useful manner. Let’s say you run an ecommerce site, and last holiday season your site experienced 10,000 page views d… I am going to divide Concurrent users load into two-part * Synchronizing Timer - pause threads unless a certain number will be reached and fire them all at the same time. 59.0172 / 720 (30 days in November x 24h per day = 720) =.08 average concurrent users in November However, if you calculate the average concurrent sessions for … If you want to stress your application with Apache JMeter you will try to start a load/performance test from JMeter with a lot of threads or concurrent users. To check all threads were started simultaneously use listeners. These performance tests are very basic tests where there is only single HTTP request (per user). In the next field, the Ramp-Up Period, leave the default value of 1 seconds. To clarify my question: What I am trying to figure out here is let say I put number of threads = 500, and ramp-up time = 0. So to reach 10K transactions, you’d need: (10k/30) = 333 users. Create a free website or blog at WordPress.com. https://serverfault.com/questions/381936/how-to-know-how-many-concurrent-users-jmeter-can-start/381942#381942. How to know how many concurrent users jMeter can start. This graph will display the hits generated by the test plan to the server per second. Although I can trial & error to find out the numbers, I hoping if there is a way to pre-calculate it. Generic Thread Group element along with setUp Thread Group and tearDown Thread Group comes by default with Apache JMeter package. That means a single user will execute (60/2) = 30 transactions in an hour. The scope of this article is to demonstrate how to perform load testing of RESTful APIs using Apache JMeter.
