total users vs concurrent users

( Log Out /  Logically when we do any performance improvement the concurrent users should increase rather than decrease. For PlayStation 4 on the PlayStation 4, a GameFAQs message board topic titled "Steam only has 12 million concurrent users vs. PS4 21 million ? However a noticeable point is in an hour a user runs for only 10 mins and is inactive for most of the time. Test Plan 1 – Login 1,590 users. 750 clerical logged in users x 2 offices = 1,500 Concurrent users are defined as the total number of people using an online resource in a particular location within a predefined period of time. for a span of time. active users. 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. Completely login all users before advancing to Test Plan 2. Hi Motoma, Sorry for confusing you. Example: 250 visits per 1 day Named users are all of the users authorized to use IBM Cognos BI; that is, your total user population. But there’s one more consideration. named users. Not necessarily. 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. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. any insights would help me in making sure I implement support in my application that is on par for the demand. Actually i have been told to calculate concurrent users day. Many of our clients have enterprise applications that are accessed 24 hours a day, seven days a week. We’re beginning to get a range for the number of concurrent users for a load test. The LoadStorm test parameters simulate “concurrent” users not total users. Change ), You are commenting using your Facebook account. Not all of our users will be active in the application simultaneously. 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. However, we’re not quite through. (total monthly users)/(30 days a month * 15 hours a day * 4 {note, 60min/15min per user} = daily average concurrent user load. To find out which users are Named Users - the Employee business object includes a Boolean field called 'Is Named User'. Load Testing - Frequently Asked Questions. 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). 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. Thus I again use the formula to calculate the Average Concurrent Users, which comes around 15. The tag defines concurrency as a manner of running two processes simultaneously, but I thought parallelism was exactly the same thing, i.e. : separate threads or processes which can potentially be run on separate processors. Number of virtual users = 10 * 10 * 3600 / 600 = 600. 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. • Workflow 2 – 470 users adding new records in the application; Change ), You are commenting using your Twitter account. So we’ll apply some statistical logic to arrive at a realistic number of concurrent users for a peak load test. That would assume that 100% of all potential users are logged in at the same time. Concurrent Users refers to the total number of users who perform the same operation or transaction exactly at the same point of time. Each office has 2,000 employees. Let’s say Medical Provider Incorporated (a fictitious company) has offices in Munich, New York and Los Angeles. 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. What is the difference between the terms concurrent and parallel execution? A subset of active users, concurrent users are simultaneously demanding system resources. 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. • Workflow 3 – 124 users querying records in the application. 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. I have searched extensively to try and get some figures on how many concurrent users SharePoint can typically handle but havent had much luck. For example : At a specific point of time, a subset of registered users would be accessing the system during a sales season. Change ), USE WINDOWS SERVER TO PERFORM A SIMPLE MULTI-USER LOAD TEST WITH APPLOADER ». If my total number of threads are 100 i.e 100 requests are being sent to application with say in 100 seconds. You are currently reading Understanding the Difference between Total Users and Concurrent User at nrgglobal. 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. For our example, we’ll say 1,000 in each office. Albuquerque, New Mexico. "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 … What is the total amount of users that can be loaded in the AD or Exchange. Concurrent Users share a finite amount of licenses. 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. In such cases, total users could number in the thousands. 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. There is a big difference between simultaneous and concurrent users in load testing world. 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. Here’s the math: 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. 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. 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. Concurrent User License Sample set of 40 Licenses. 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. 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. here at any point in the scenarion no 2 users are logged in to the system. 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. 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. You can calculated concurrent users with the following formula. 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. Now I made some performance improvement and the Average Visit comes down to 1.2 minutes. Each concurrent user will last for the duration of the script. If a concurrent user runs a single-user desktop and additional published desktops and applications, the user is counted only once. Each office has 2,000 employees. I expect a lot of users … 250 query logged in users x 2 offices = 500 There will be around 200 logins per day, in that i need to calculate concurrent logins per day. All rights reserved. Change ), You are commenting using your Google account. Users spending on the page about 15 min, and the site is generally accessed between 9AM EST and 6PM PST (15 hours). All online resources—websites and other services—are hosted on web and application servers at data centers, hosting companies, or cloud computing centers. So our load test will feature 1,590 logged in users. 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. Let’s do some quick math: It is usually calculated with a short time period of 1 to 30 minutes.
