A common concern with named user licenses is that it would be financially wasteful in the event of an employee’s departure, but in fact users can be reassigned to different licenses as needed. Notice that once all 25 concurrent users are logged in and doing work, the throughput stays fairly consistent. All the requests of the elements in a web page are recorded in-between these concurrent group functions. Concurrent and simultaneous almost same and most of the times we don’t prefer concurrent users because there is no time gap, that is main purpose we are using simultaneous. The request will be send continuously without pacing. Also since what users do usually takes time. It seems like on every new project, there is a need to educate members of the project team on the difference between concurrent users and simultaneous users as it applies to load testing applications. These parallel concurrent calls can be simulated in Loadrunner using web_concurrent_start & web_concurrent_end functions. Simultaneous = users executing the same code at the exact same time. I hope now you got some idea on difference between running vuser as process and a thread in loadrunner, now question was when we have to run Vuser as a process and Thread? 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. Each concurrent user will last for the duration of the script. Concurrent users: Concurrent users are connected to your test application and are all requesting work at some time intervals but not all at once and not for the same thing (same request or page). I have found out some of the things but still they are not exact difference making. The concurrent licenses are global and shared by anyone who needs to use the system. Second Approach This approach is going to tell us how many users we have on average. They might be active and in-active. In addition, concurrent has a few additional meanings, most of which amount to "in agreement," as in "two people working concurrently." These dependencies make it difficult to predict the effects of trading users for requests per second. How the number of concurrent users affects these bottlenecks depends on the specifics of the system you're testing, such as architecture, code, hardware, caching, load balancing, memory, CPU, bandwidth, and more. In loadrunner concurrency between the user transactions can be achieved by introducing randomized think time (lr_think_time) and the end of transactions. All the concurrent users would perform login, reports download, etc at the same point of time. Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time. Can anyone tell me exact difference between all of this with example. Simultaneous Users: When multiple users access a website and Perform the same action at the same time is called simontenious users. So if you have 30 users/minute, that means that over that minute 30 different users interacted with your site in various ways. To make users simultaneous LR has given "Rendezvous Point" feature. Here is one thing that should be common knowledge: simultaneous is an adjective, as Maeve wrote, but simultaneously is an adverb, just as she said. However, “Common sense ain’t as common as it used to be”. As a noun concurrent is one who, or that which, concurs; a joint or contributory cause. Typically concurrency is … When the application is a thick client (like Citrix, RTE, RDP, SAP GUI, Ajax true client, QTP) and needs a lot of client memory we have to run Vuser as process. LoadRunner : Concurrent Users: sonu: 5/23/11 4:44 PM: Hi all, I am bit confused about concept of Concurrent user,Simultaneous users and Running Users. According to this blog post at least JMeter has some problems. I've had bad experiences with load testing tools (LoadRunner and JMeter) because those tools doesn't seem to simulate modern web browsers correctly. Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time. Adjectives and adverbs have different uses. The other meaning of concurrent is related to geometry, where you might say two lines were concurrent: they're going to intersect at a common point. This is expected. There are three components in Loadrunner: ... What is the difference between Simultaneous and concurrent users? … Thus we need a better way of calculating the required load in such a way that the production load is met without increasing the cost of the tool (and thus the test). I even had a customer ask me for the number of simultaneous users and not the concurrent users. > > > > > > > > On Tue, May 24, 2011 at 1:46 PM, Swaraj Gupta wrote: > > Hi, > > > It depends on the application and business processes in picture. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. Ok. Moreover tool licensing are planned in such a way that more the number of concurrent users you require, more is the cost of license. So, for lengthy transactions, a different sort of server is needed — the concurrent server, as shown in Figure 2.Here, Client A has already established a connection with the server, which has then created a child server process to handle the transaction. How to calculate memory requirement for Vusers in LoadRunner. 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. Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time. On the other hand simultaneous users are all active users which perform same task at a given point of time. Average Concurrent Users = Visits per hour / (60 min/hour / average visit. Simultaneous users are the users who have a valid session in the server. Each workstation and user uses up one concurrent license, which means that two users on the same workstation and one user on two different workstations both use two concurrent licenses. This allows the server to process Client B’s request without waiting for A’s transaction to complete. So if your Web/HTTP Vuser takes 5MB when running as a process, 50 Vusers would take 250 MB. > Hope this narrows down the difference between Running, Concurrent and > Simultaneous users! Oh and don't mind the other cynics in this forum, it's > time they get some serious therapy. Concurrent = users on the system using resources. Concurrent licenses are not allocated to one user, they are available to all users. Q14. Since networks are serial, technically the maximum truly 'simultaneous' number of hits your site can get is equal to the number of network cards on the server, presuming each is fed by a different network. That is to say, they're working towards the same goal. LoadRunner : Concurrent Users Showing 1-7 of 7 messages. Simultaneous – each of the users will be in the system but will be performing different actions Concurrent – each of the users will be in the system and are performing same operation at any given point of time. What are different types of Loadrunner components? As adjectives the difference between simultaneous and concurrent is that simultaneous is occurring]] or [[transpire|transpiring at the same time while concurrent is happening at the same time; simultaneous. I know there is "Use concurrent pool" setting in JMeter and you can simulate different browsers in LR, but what is your experience, are those really working like they should? 1. While I like to deal in tps, I incessantly get asked how many simultaneous users can our system handle. Each of the users would be performing different actions like one doing login , other viewing the reports, etc. Concurrent Users: When multiple users access a website but perform different-different actions at the same time is called concurrent users. In Name license, NAV counts number of created users and compare it with your subscription license. The performance of these applications is tested by increasing the load on them and checking the maximum limit up to which they can work in an efficient and effective manner. 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 a company. 2. Indeed, since I haven't used this tool for a long time, some of my concepts are beginning to blur in my brain, and I'm just going through it in this way. Users per minute is different from concurrent users. Thus making the simulation more realistic. Users per minute means unique users within a period of time. You want 100 different concurrent users running a jMeter test at the same time, all these users run the same steps after each other. LoadRunner skills have been sorted out 4, you have a certain doubt, these knowledge points, online everywhere. Clock concurrent optimization (CCOpt) is a revolutionary new approach to timing optimization: it merges physical optimization into clock tree synthesis and simultaneously optimizes clock delay and logic delay using a single unified cost metric. Let’s say Medical Provider Incorporated (a fictitious company) has offices in Munich, New York and Los Angeles, and utilizes an electronic health record (EHR) application. Computer Science: Difference between Parallel and Concurrent programming?Helpful? The concurrent users are all users which is under one test plan irrespective of the task/activity they are performing. JMeter vs LoadRunner. Each office has 2,000 employees. Each of the users would be performing different actions like one doing login , other viewing the reports, etc. JMeter and LoadRunner are two different performance testing tools. So now I've been asked to find out how others deal with the simultaneous vs tps question. Performance testing tools are tools in the software field by which different types of applications used in the software are tested. That means three things: Build a jMeter test for the steps. 2. Concurrent CALs license individual users to access the application only while they are consuming one of the Concurrent CALs (making it unavailable for other individuals to access the application). Simultaneous users are the users who have a valid session in the server. Memory requirement also called as Memory footprint for a Vuser can be called as a function that is dependant on Vuser type (Web, CITRIX, SAP GUI); application and system where you intend to run the test.. (I would record the steps) Running the test with 100 concurrent users, use ramp-up 0, see: JMeter concurrent users count and JMeter understanding ramp up If we use concurrent user. Below are the LoadRunner throughput chart results for a 25-user test that I recently ran. Now notice what throughput looks like on a test that did not perform as well as the last example.
