How many users can JMeter simulate?
10,000 users
In conclusion, we can say that you can simulate up to 10,000 users on a JMeter load test even on a regular laptop. This depends on following 4 simple rules: Use JMeter listeners for debugging purposes only. Run JMeter performance tests in non-GUI mode.
How does JMeter simulate multiple users?
So JMeter simulates multiple users by making copies of the samplers and running them in a separate thread. JMeter HTTP request sampler makes all the received data for further analysis. JMeter use the tree view listener for actually visualizing the received response.
How does JMeter calculate concurrent users?
In both thread groups, set the Number of Threads. This is the number concurrent users you wish to simulate. In both thread groups, set the Loop Count. This number will determine how many times each thread is run, and therefore controls the length of the test.
How many threads can JMeter handle?
JMeter allows you to run multiple processes in the same box, and it’s usually pretty reliable generating up to 200 threads per JMeter instance. If you need more than that, I’d recommend using multiple JMeter instances. A modern machine with some tweaking can easily generate 500 to 1000 threads.
What is concurrent user & simultaneous users in JMeter?
Simultaneous users can be concurrent users, but concurrent users cannot be simultaneous users. Generally, the number of concurrent users on an application is more than the number of simultaneous users. All the simultaneous users must be active and perform the same activities at a point in time.
How do I hit multiple requests in JMeter?
Show activity on this post.
- first create a thread pool under your plan and add Sampler -> HTTP Request (Right-click on TestPlan and create a thread group.
- Configure your HTTP request with your post method data and API.
- Repeat step 1 and 2 with different data.
- finally create a listener for your plan and Run.
What does 100 concurrent users mean?
In computer science, the number of concurrent users (sometimes abbreviated CCU) for a resource in a location, with the location being a computing network or a single computer, refers to the total number of people simultaneously accessing or using the resource.
How many concurrent users are needed for load test?
For HTTP (S) test each Load Injector can handle approximately up to 1000 concurrent HTTP users. For Web page or Web application test each Load Injector can handle approximately up to 25 concurrent users.
What is concurrent users in performance testing?
A concurrent user test is often used to identify bottlenecks in the performance of a website – basically to find out how many concurrent users can make requests of a website until the performance of the site is significantly degraded.
How do you calculate concurrent users?
Calculating the Number of Concurrent Users For example, if your peak visits per hour is 200 visitors and the average visit duration is 6 minutes, the number of concurrent users that should be used to create 200 visits per hour is 20 concurrent users.
What is the difference between concurrent users and simultaneous users?
Concurrent = users on the system using resources. Simultaneous = users executing the same code at the exact same time.
What is the difference between active users and concurrent users?
Concurrent connections are the number of currently open TCP/IP connections on an agent. Active users are the number of currently executing users on an agent. Each virtual user can and should have more than one concurrent connection open and this is a browser setting.
Is JMeter multithreaded?
It is the base element for every JMeter test plan. There are multiple thread groups available which can be configured to simulate how the users interact with the application, how the load is maintained and over what period of time.
Can we run two threads simultaneously in JMeter?
Yes, You can create multiple test cases in Jmeter. We can add multiple Thread group as test cases under Test plan.
What server size do I need for 10000 users?
The server need to handle 10,000 concurrent users for a application with MySQL database request. Depends on what these connections are doing. If it is just an API call, it can run on a normal digital ocean server with 8 GB ram .
How do you calculate number of concurrent users?
How do you calculate number of users in performance testing?
Performance testers, depend on the business teams to give the idea about the concurrent user load required for the application to be tested….Here:
- Number of users per hour = 10.
- Number of requests per user = 10 (number of web pages he accesses)
- Length of user scenario = 10 min * 60 = 600 sec.
What are listeners in JMeter?
A listener is a component that shows the results of the samples. The results can be shown in a tree, tables, graphs or simply written to a log file. To view the contents of a response from any given sampler, add either of the Listeners “View Results Tree” or “View Results in table” to a test plan.
Does JMeter run requests sequentially?
Requests are always been executed sequentially, i.e. each virtual user will execute Request 1 then Request 2 on first iteration then execute Request 1 and Request 2 on second iteration, etc.
