At present I have 52 users in list. 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! and the whole thing multiplied by 50% to suggest a 50% chance of those total users online executing a request at roughly the same time. Do we need to run a 2,000 user load test? Each concurrent user will last for the duration of the script. Of the 1,000, let’s say 750 clerical users login to the application at the beginning of their day, add and update records, then log out at the end of the day. Hi Motoma, Sorry for confusing you. Concurrent user licensing is often much more affordable than total/named user licensing, especially when users only need to access to the … All rights reserved. Edwer Fang [MSFT] MSDN Subscriber Support in Forum If you have any feedback on our support, please contact msdnmg @ microsoft.com Please remember to mark the replies as answers if they help and unmark them if they provide no help. I think that the maximum user count is related about the virtual user limitation of VS load test. total user ID codes). And now, based on the above example, here’s the recommended Test Case: Not all of our users will be active in the application simultaneously. If you don't yet see data in the users, sessions, or events blades in the Application Insights portal, learn how to get started with the usage tools. ( Log Out /  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. For example, if you have a test with one script having one page, starting at 10 concurrent users and peak of 10 concurrent users for 20 minutes, there will be 200-300 total users simulated (and same number of sessions). Each office has 2,000 employees. Test Plan 2 – Perform the following workflows simultaneously: A subset of named users, active users are logged on to IBM Cognos BI and can demand system resources. named users. Change ), USE WINDOWS SERVER TO PERFORM A SIMPLE MULTI-USER LOAD TEST WITH APPLOADER ». ( Log Out /  All online resources—websites and other services—are hosted on web and application servers at data centers, hosting companies, or cloud computing centers. "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 … 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. 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 … I've never quite been able to grasp the distinction. Concurrent Users:. The LoadStorm test parameters simulate “concurrent” users not total users. 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. 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. There is a similar thread, please also go through it to help troubleshoot this issue: Total AD Concurrent Logins 750 clerical logged in users x 2 offices = 1,500 (total monthly users)/(30 days a month * 15 hours a day * 4 {note, 60min/15min per user} = daily average concurrent user load. if you stop and restart your broadcast, this number will return to zero. LOL PC trolls". 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. Change ), You are commenting using your Facebook account. For our example, we’ll say 1,000 in each office. • Workflow 1 – 470 users updating existing records in the application; The LoadStorm test parameters simulate “concurrent” users not total users. The other 250 query users login only when they need to do a query, then logout. Hence the above formula gives a user count of 600 users. This graph shows the number of users logged in to PCS device. I need to load upto 75 users but only connect upto 50 concurrent. Number of virtual users = 10 * 10 * 3600 / 600 = 600. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. For example, if you successfully run a 100-user test, then see a value of 50 for Max Users , that means of the your 100 users that ran, 50 of them ran simultaneously. ( Log Out /  So for me to guess the concurrent users on a peak hr, am doing below math. We are setting up a SharePoint 2010 Web Application which will roughly have 30,000+ total users and the number of concurrent users using the system can be extremely high. It is usually calculated with a short time period of 1 to 30 minutes. Each store will have 4 users which constitute to 13680 total users. Thus Average Concurrent User comes around 20. Their applications may be accessed remotely from all over the world. Sales & Support: 1 (505) 503-6249 Many of our clients have enterprise applications that are accessed 24 hours a day, seven days a week. 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. So requests are made to server but is there any formula which can give concurrent users ( Log Out /  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. The tag defines concurrency as a manner of running two processes simultaneously, but I thought parallelism was exactly the same thing, i.e. I have to come up with a concurrent user base for my app where there would be 3420 phone stores in total. In the above example, this user can log in twice concurrently with the same username. Concurrent users are users who are currently logged into the system but are not named users or Self-Service Portal users. for a span of time. 250 query logged in users x 2 offices = 500 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. You can calculated concurrent users with the following formula. Named users are all of the users authorized to use IBM Cognos BI; that is, your total user population. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. Completely login all users before advancing to Test Plan 2. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. There will be around 200 logins per day, in that i need to calculate concurrent logins per day. Simultaneous users: Lets say that users are logging into application, send a mail and logout. 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. 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. Let’s do some quick math: First, determine the number of employees that actually access the enterprise application under test. 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 … Remote workers are webmail only, Any help in licence efficiencies would be helpful Concurrent Users: The word concurrent is used only for the events that occur over a period of time i.e. 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. Let’s say Medical Provider Incorporated (a fictitious company) has offices in Munich, New York and Los Angeles. 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. The starting and peak number of virtual users in LoadStorm represent concurrent users or the number of simulated users at a particular point in time. Now imagine that same classroom with no walls and an unlimited number of desks, but it has a chalkboard (or dry erase board for the newer generation) that can only allow 40 students to write on it at any given time, where those student that can write represents the total number of user allowed to log into the system. What is the difference between the terms concurrent and parallel execution? Working out the number of Concurrent users in a load test . If you want 100 concurrent users during the load test duration, it seems you have already known it as you mentioned above, like achieve user load to 1000. • Workflow 3 – 124 users querying records in the application. So our load test will feature 1,590 logged in users. Total Viewers: Shows how many viewers have watched the stream since the current broadcast began. One Hr users = 13680/8hrs = 1710. What is the total amount of users that can be loaded in the AD or Exchange. 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. 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. © 2008-2021 LoadStorm, LLC. Concurrent User License Sample set of 40 Licenses. For example : At a specific point of time, a subset of registered users would be accessing the system during a sales season. Hence the users which are running under a test plan; irrespective of the activities they are doing; are ‘Concurrent Users’. You are currently reading Understanding the Difference between Total Users and Concurrent User at nrgglobal. 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. At 9:00 AM when the Los Angeles office opens, it’s noon in New York, but it’s already 6:00 PM in Munich. Concurrent Views: Displays how many viewers are watching the stream at each second.As viewers join and leave the stream, this number will fluctuate up and down. A subset of active users, concurrent users are simultaneously demanding system resources. Concurrent Users: Users with an active session on PCS (logged in), across the cluster VPN Tunneling users: Users with active VPN Tunneling sessions across the cluster Local VPN Tunneling users: Users with active VPN Tunneling session on the specific node Local users: Users with an active session on … We still need to account for the actual concurrent user activity. Concurrent users are defined as the total number of people using an online resource in a particular location within a predefined period of time. Performance Testing, Simultaneous User, Concurrent Users, Difference between Simultaneous Users and Concurrent Users, Performance Testing Basics, Simultaneous Vs Concurrent Each office has 2,000 employees. If a concurrent user runs a single-user desktop and additional published desktops and applications, the user is counted only once. active users. In the performance testing term, you would say ‘a period of time’ implies ‘test duration’. There is a big difference between simultaneous and concurrent users in load testing world. tl;dr — This post is about using Google Analytics to determine how many concurrent users to specify in your load tests. Now I made some performance improvement and the Average Visit comes down to 1.2 minutes. any insights would help me in making sure I implement support in my application that is on par for the demand. As my understanding, what you actually want to know may be how many virtual users you need to simulate. I expect a lot of users … Concurrent Users share a finite amount of licenses. concurrent users. Not necessarily. Actually i have been told to calculate concurrent users 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. Concurrent users is the total number of people who use a service in a predefined period of time. Logically when we do any performance improvement the concurrent users should increase rather than decrease. Concurrent Users refers to the total number of users who perform the same operation or transaction exactly at the same point of time. Thus I again use the formula to calculate the Average Concurrent Users, which comes around 15. 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. Be sure to analyze your environment carefully to determine your meaningful load test user requirements. 1425 x .33 = 470 (updating); 1425 x .33 = 470 (adding); 165 x .75 = 124 (queries) 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. If Munich closes at 6:00, the peak load for our application need only include two offices accessing the application at the same time. Let’s say Medical Provider Incorporated (a fictitious company) has offices in Munich, New York and Los Angeles. We’re beginning to get a range for the number of concurrent users for a load test. here at any point in the scenarion no 2 users are logged in to the system. However a noticeable point is in an hour a user runs for only 10 mins and is inactive for most of the time. 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. Example: 250 visits per 1 day That would assume that 100% of all potential users are logged in at the same time. I have been informed by Microsoft that 50 users is max on std and 75 on premium. Here’s the math: 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. 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. Be sure to analyze your environment carefully to determine your meaningful load test user requirements. However, we’re not quite through. Users spending on the page about 15 min, and the site is generally accessed between 9AM EST and 6PM PST (15 hours). In this process, every user will wait for the other user to complete the entire transaction before logging. Change ), You are commenting using your Google account. 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. : separate threads or processes which can potentially be run on separate processors. I have searched extensively to try and get some figures on how many concurrent users SharePoint can typically handle but havent had much luck. Change ), You are commenting using your Twitter account. Load Testing - Frequently Asked Questions. Logged in users, even if dormant, still require system resources so it’s important to test with an adequate number of logged in users. Email: support@loadstorm.com But there’s one more consideration. • Workflow 2 – 470 users adding new records in the application; If my total number of threads are 100 i.e 100 requests are being sent to application with say in 100 seconds. If this is checked, then the user is a Named User. So we’ll apply some statistical logic to arrive at a realistic number of concurrent users for a peak load test. For PlayStation 4 on the PlayStation 4, a GameFAQs message board topic titled "Steam only has 12 million concurrent users vs. PS4 21 million ? Tagged: Application Testing, application testing; performance testing, Concurrent Users, load testing, Test Case, Test Plan. 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.
