Number of virtual users = 10 * 10 * 3600 / 600 = 600. The LoadStorm test parameters simulate “concurrent” users not total users. You can calculated concurrent users with the following formula. What is the difference between the terms concurrent and parallel execution? So our load test will feature 1,590 logged in users. That would assume that 100% of all potential users are logged in at the same time. In the above example, this user can log in twice concurrently with the same username. Tagged: Application Testing, application testing; performance testing, Concurrent Users, load testing, Test Case, Test Plan. The tag defines concurrency as a manner of running two processes simultaneously, but I thought parallelism was exactly the same thing, i.e. LoadStorm will create a new session for each virtual user, but it will not maintain the session after the script has ended, so your session should time out as you have configured it. Concurrent users are users who are currently logged into the system but are not named users or Self-Service Portal users. The other 250 query users login only when they need to do a query, then logout. named users. : separate threads or processes which can potentially be run on separate processors. 250 query logged in users x 2 offices = 500 ( Log Out /  Albuquerque, New Mexico. The total simulated users will generally be much higher than concurrent users, but the actual count depends on lots of other factors such as the number of pages in the script, think times, etc. here at any point in the scenarion no 2 users are logged in to the system. If Munich closes at 6:00, the peak load for our application need only include two offices accessing the application at the same time. Each store will have 4 users which constitute to 13680 total users. Example: 250 visits per 1 day Hi Motoma, Sorry for confusing you. Change ), You are commenting using your Twitter account. When configuring a test plan for our clients we want to establish a realistic number of concurrent users, in other words, the number of users actually in the system, actively using the application at a given time. Not all of our users will be active in the application simultaneously. There will be around 200 logins per day, in that i need to calculate concurrent logins per day. Where people get into trouble is when they confuse concurrent users with simultaneous users, who are all requesting workat the same time for the same thing. There is a similar thread, please also go through it to help troubleshoot this issue: Total AD Concurrent Logins Remote workers are webmail only, Any help in licence efficiencies would be helpful As my understanding, what you actually want to know may be how many virtual users you need to simulate.

Email: support@loadstorm.com A subset of named users, active users are logged on to IBM Cognos BI and can demand system resources. Logically when we do any performance improvement the concurrent users should increase rather than decrease. Although not all 1,590 users will be active in the application, the fact that they’re logged into the application means that their imposing a load on the resources. In such cases, total users could number in the thousands. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. I expect a lot of users … Load Testing - Frequently Asked Questions. Concurrent user licensing allows firms to purchase computer systems and software at a lower cost because the maximum number of concurrent users expected to use the system or software at any given time (those users all logged in together) is only a portion of the total system users employed at … Here’s the math: Concurrent Users:. ( Log Out /  Thus Average Concurrent User comes around 20. Hence the users which are running under a test plan; irrespective of the activities they are doing; are ‘Concurrent Users’. Concurrent Session Based License (CSBL) is a welcome return for companies that have a mix of Internal users and/or are using their Business Objects platform to provide embedded reporting service an unknown number of “generic public” users via the Java or .Net SDK. Each office has 2,000 employees. 1425 x .33 = 470 (updating); 1425 x .33 = 470 (adding); 165 x .75 = 124 (queries) So, in summary, on the surface we might have assumed that a 6,000 user load test would be required for Medical Provider Incorporated to adequately load test their application. What is the total amount of users that can be loaded in the AD or Exchange. Anyone who works in an office knows that 100% of the employees are rarely in the office at the same time, let alone sitting at their desks hammering away at an application.

(total monthly users)/(30 days a month * 15 hours a day * 4 {note, 60min/15min per user} = daily average concurrent user load. Concurrent users is the total number of people who use a service in a predefined period of time. If you want to measure concurrent users, you'd have to find some way to count the current logon/logoff session or find some third party tool. Performance Testing, Simultaneous User, Concurrent Users, Difference between Simultaneous Users and Concurrent Users, Performance Testing Basics, Simultaneous Vs Concurrent First, a note about the Max Users measurement, as seen in the above screenshot: Max Users refers to the maximum concurrent (simultaneous) users achieved during the test. At present I have 52 users in list. Sales & Support: 1 (505) 503-6249 So, in this example, we would need a total of 3 user/device licenses, even though we have 4 individual users and 6 individual devices in the mix.

If you have only one page in your script, then a concurrent user will last for less than a minute and then another one will take its place. any insights would help me in making sure I implement support in my application that is on par for the demand. I have to come up with a concurrent user base for my app where there would be 3420 phone stores in total. Concurrent Users: The word concurrent is used only for the events that occur over a period of time i.e. Simultaneous users: Lets say that users are logging into application, send a mail and logout. Test Plan 1 – Login 1,590 users. Concurrent Connection Limits a maximum number of open connections which can be set for each user entry by checking the Maximum concurrent connections check box and entering a number in the accompanying field. I need to load upto 75 users but only connect upto 50 concurrent. I've never quite been able to grasp the distinction. So we’ll apply some statistical logic to arrive at a realistic number of concurrent users for a peak load test. • Workflow 3 – 124 users querying records in the application. The total simulated users will generally be much higher than concurrent users, but the actual count depends on lots of other factors such as the number of pages in the script, think times, etc. With “simultaneous” or “concurrent” user licensing, you only need to buy a license for the number of people who will be using the system at the exact same time, which is typically much less than the total number of “named” users (i.e. But thinking from a server point of view, the server doesn't differentiate whether a single user has sent 100 requests within 1 hour or … In this process, every user will wait for the other user to complete the entire transaction before logging.
