The term concurrent user refers to more than one user utilizing a computer resource at the same time (or in the same predefined period of time). Commercial software may restrict the number of concurrent users depending on the type of software license purchased for the system.
.
Simply so, what is the difference between concurrent users and simultaneous users?
Simultaneous users are the users who have a valid session in the server. Each of the users would be performing different actions like one doing login , other viewing the reports, etc. Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time.
Similarly, how does Jmeter calculate concurrent users? How to Calculate Target Concurrent Users. A common method is to divide the number of unique users by the average visit duration for a given period. For example, 12,000 unique visitors per hour / ( 60 minutes / 15 minutes per visit ) would equal 3,000 concurrent users.
Consequently, how do you measure concurrent users?
2 Answers. If you have an average visit length of 5 minutes, a single user could create 60 min / 5 min = 12 visits per hour. To get to the target number of 1000 visits/visitors per hour, you need 1000 visits / 12 visits per user = 84 concurrent user. In total you will have 1000 visits and 3000 page views.
What is concurrent session?
"Concurrent" means occurring at the same time. "Session" can be any voice or video communication between two communicating devices/services. Usually, the number of concurrent sessions is equal to the number of lines that you need for the communication (e.g., phone lines).
Related Question AnswersWhat is mean by concurrent users in performance testing?
The idea behind concurrent user testing is to identify the response time of a website for a specified number of simultaneous users making requests to a website. Concurrent user testing measures how long it takes the server to respond to a specified number of simultaneous requests.What are concurrent connections?
Concurrent connections means the total number of simultaneous connections you can have open across you channels account. For example: 1) User A connects to your Channels app - that is one concurrent connection. 2) User B connects to your Channels app as well - that is two concurrent connections.What is named user license?
A named user license is an exclusive licensure of rights assigned to a single named software user. The user will be named in the license agreement. Named user licenses can be composed of "single seat licensures," more commonly known as "volume license accounts".How many users can JMeter simulate?
it would be best to use distributed jmeter and simulate distributed '10000 users' for creating load. This is depends on how you design your test case. I have tested 500-8000 concurrent user per host depends on host power. in aws, i used to test 500 concurrent users for 7.5GB/4Core Xeon aws.What is concurrent testing and how will you perform?
Concurrent testing is performed to test the stability of a software product when the multiple number of users access and utilise its services, at a same time. This helps in getting a rough idea of the problems arising out of multiple usages such as increased response time, crashes, deadlocks and throughputs.What is concurrency in load testing?
Concurrency Testing is defined as a testing technique to detect the defects in an application when multiple users are logged in. In other words monitoring the effect while multiple users perform the same action at the same time.What is concurrent users in JMeter?
'Also JMeter concurrent threads are not "concurrent users" as real-life people do pauses between actions on web pages. If you don't set any pauses in your tests then 20 concurrent threads will stand for something like 200-250 concurrent users. They are thinking 50 Threads = 50 Users.What are virtual users in performance testing?
Simply: Virtual users (VUs) are concurrent users that are able to open multiple connections in parallel during a test. Virtual Users constantly iterate through their user scenario until the test is over. A small number of Virtual Users can create a number of sessions magnitudes greater than their total.How is user load calculated 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.
How is server throughput calculated?
Throughput measures the amount of messages that a server processes during a specific time interval (e.g. per second). Throughput is calculated by measuring the time taken to processes a set of messages and then using the following equation.How is server load capacity calculated?
Seconds per Request- Requests per second: 30 (H)
- Load-balanced servers: 3 (V)
- Concurrents requests per server: 20 (Q)
- Seconds per Request (per server per concurrent connection), L = (1 / H) * V * Q = (1 / 33.333) * 3 * 22 = 2 seconds.
How do I create a virtual user for load testing?
To create a virtual user:- Open your test in the Load Test Editor. To do this, double-click the needed test in the Project Explorer panel.
- Click New Item on the editor's toolbar or press Insert on the keyboard.
- Specify virtual user properties. See About Load Test Editor.
