What is the difference between concurrent and simultaneous User?
Concurrent users tell the number of users for a given test duration, while simultaneous users define the number of users performing the same transaction at any given point of time.
What is meant by concurrent users in performance testing?
Concurrent Users. Throughput is a measure of how many units of work are being processed. In the case of load testing, this is usually hits per second, also known as requests per second. Concurrent users are the number of users engaged with the app or site at a given time.
What is meant by concurrent users?
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 users can be on a website at once?
It is great that you want to know the answer, but there is not a single hard and fast rule to provide it for you. You have several limits: Ports: max 65536, practically less, the first 1024 are reserved, if you need more, you need several NIC (Network Interface Card) or several servers for load balancing.
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.

The simultaneous user is a subset of the concurrent user. 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.
What’s the difference between simultaneous and concurrent HTTP requests?
Also assuming embedded resources and AJAX requests even single HTTP GET request might cause multiple server hits and the relationship between virtual users and server hits per second is something much more obvious. simultaneous = same action, same time. “Everyone push the enter button in 3, 2, 1, Now!”
When do you use the word simultaneous users?
The word simultaneous is used for the events that occur at a point in time. In the performance testing when you instruct all the users to perform the same transaction together then at that particular point those users become ‘Simultaneous Users’.
What’s the difference between simultaneous and concurrent load testing?
Given certain virtual users concurrency some of the “load test steps” can be (and given more or less high load will be) simultaneous. Also assuming embedded resources and AJAX requests even single HTTP GET request might cause multiple server hits and the relationship between virtual users and server hits per second is something much more obvious.
