total users vs concurrent users

Posted on January 12th, 2021

So our load test will feature 1,590 logged in users. • Workflow 2 – 470 users adding new records in the application; Concurrent Users: The word concurrent is used only for the events that occur over a period of time i.e. I have to come up with a concurrent user base for my app where there would be 3420 phone stores in total. Be sure to analyze your environment carefully to determine your meaningful load test user requirements. The other 250 query users login only when they need to do a query, then logout. Concurrent User License Sample set of 40 Licenses. Remote workers are webmail only, Any help in licence efficiencies would be helpful 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. Change ), You are commenting using your Twitter account. any insights would help me in making sure I implement support in my application that is on par for the demand. I've never quite been able to grasp the distinction. However, we’re not quite through. Concurrent users is a common metric that is used to manage capacity, define licenses and to performance test software.The following are illustrative examples of concurrent users. Number of virtual users = 10 * 10 * 3600 / 600 = 600. Logically when we do any performance improvement the concurrent users should increase rather than decrease. Their applications may be accessed remotely from all over the world. Sales & Support: 1 (505) 503-6249 Users spending on the page about 15 min, and the site is generally accessed between 9AM EST and 6PM PST (15 hours). 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. And now, based on the above example, here’s the recommended Test Case: Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. However, by differentiating between total users and concurrent users, we find that a realistic and meaningful load test would login 1590 users, of which 1,064 would execute actions within the application. Actually i have been told to calculate concurrent users day. Do we need to run a 2,000 user load test? Not necessarily. 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. Now I made some performance improvement and the Average Visit comes down to 1.2 minutes. We’re beginning to get a range for the number of concurrent users for a load test. for a span of time. For our example, we’ll say 1,000 in each office. Total Viewers: Shows how many viewers have watched the stream since the current broadcast began. That would assume that 100% of all potential users are logged in at the same time. 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. Working out the number of Concurrent users in a load test . There is a big difference between simultaneous and concurrent users in load testing world. 750 clerical logged in users x 2 offices = 1,500 Tagged: Application Testing, application testing; performance testing, Concurrent Users, load testing, Test Case, Test Plan. To arrive at the number of logged in users, let’s say 95% of clerical users and 33% of query users are logged in at once, therefore: (1,500 x .95) = 1425; (500 x .33) = 165; Total logged in users = 1,590. I expect a lot of users … Thus I again use the formula to calculate the Average Concurrent Users, which comes around 15.

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. We still need to account for the actual concurrent user activity. The concurrent user approach is more flexible, but does require us to make some assumptions to compare with the named users in the previous example: The business executives login for only 5-10 minutes each per week, so they can share a license with each other or one of the other team members. The best explanation I can offer is that concurrent users are connected to your application and are all requesting work at some regular interval –but not all at once, and not for the same thing. So, again, applying some statistical logic, let’s say 33% of the clerical users are concurrently adding records and 33% are updating records, and 75% of the query users are performing queries simultaneously. Concurrent Users refers to the total number of users who perform the same operation or transaction exactly at the same point of time. 1425 x .33 = 470 (updating); 1425 x .33 = 470 (adding); 165 x .75 = 124 (queries) If Munich closes at 6:00, the peak load for our application need only include two offices accessing the application at the same time. I need to load upto 75 users but only connect upto 50 concurrent. There is a similar thread, please also go through it to help troubleshoot this issue: Total AD Concurrent Logins First, determine the number of employees that actually access the enterprise application under test. But there’s one more consideration. So for me to guess the concurrent users on a peak hr, am doing below math. • Workflow 1 – 470 users updating existing records in the application; Thus Average Concurrent User comes around 20.

Not all of our users will be active in the application simultaneously. "Hourly Sessions x Average Session Duration (in seconds) / 3,600" is the formula we recommend to get started It’s always good to take the guesswork … Because of the time differences between the three offices, there are times when users from one office will be active, while users from other offices will be home sleeping! For example : At a specific point of time, a subset of registered users would be accessing the system during a sales season. There will be around 200 logins per day, in that i need to calculate concurrent logins per day. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. active users. The LoadStorm test parameters simulate “concurrent” users not total users. USE WINDOWS SERVER TO PERFORM A SIMPLE MULTI-USER LOAD TEST WITH APPLOADER. 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. 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. This graph shows the number of users logged in to PCS device. Given that the price point for a concurrent license is 2x that of a user/device license, this small sample organization would absolutely benefit from user/device licensing as they may need as many as 4 concurrent users licenses.
