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). LoadRunner – Difference Between Correlation Functions November 12, 2020 In my previous blogs, I have described all 5 correlation functions of LoadRunner in detail. 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. That is to say, they're working towards the same goal. Concurrent = users on the system using resources. 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. 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? So if your Web/HTTP Vuser takes 5MB when running as a process, 50 Vusers would take 250 MB. 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). These parallel concurrent calls can be simulated in Loadrunner using web_concurrent_start & web_concurrent_end functions. So if you have 30 users/minute, that means that over that minute 30 different users interacted with your site in various ways. I've had bad experiences with load testing tools (LoadRunner and JMeter) because those tools doesn't seem to simulate modern web browsers correctly. Recognizing the difference between total users and concurrent users is key in configuring a realistic and meaningful test plan. Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time. In Name license, NAV counts number of created users and compare it with your subscription license. Now notice what throughput looks like on a test that did not perform as well as the last example. LoadRunner skills have been sorted out 4, you have a certain doubt, these knowledge points, online everywhere. Q14. Can anyone tell me exact difference between all of this with example. 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. Also since what users do usually takes time. > Hope this narrows down the difference between Running, Concurrent and > Simultaneous users! 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. Each of the users would be performing different actions like one doing login , other viewing the reports, etc. 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. 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. JMeter vs LoadRunner. 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. Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time. (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 There are three components in Loadrunner: ... What is the difference between Simultaneous and concurrent users? Performance testing tools are tools in the software field by which different types of applications used in the software are tested. 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 even had a customer ask me for the number of simultaneous users and not the concurrent users. 2. Users per minute is different from concurrent users. Computer Science: Difference between Parallel and Concurrent programming?Helpful? The concurrent licenses are global and shared by anyone who needs to use the system. 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. Simultaneous users are the users who have a valid session in the server. What are different types of Loadrunner components? All the concurrent users would perform login, reports download, etc at the same point of time. 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. 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. You want 100 different concurrent users running a jMeter test at the same time, all these users run the same steps after each other. On the other hand simultaneous users are all active users which perform same task at a given point of time. All the requests of the elements in a web page are recorded in-between these concurrent group functions. How to calculate memory requirement for Vusers in LoadRunner. Each of the users would be performing different actions like one doing login , other viewing the reports, etc. Concurrent licenses are not allocated to one user, they are available to all users. Thus making the simulation more realistic. Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time. Typically concurrency is … So now I've been asked to find out how others deal with the simultaneous vs tps question. In addition, concurrent has a few additional meanings, most of which amount to "in agreement," as in "two people working concurrently." LoadRunner : Concurrent Users Showing 1-7 of 7 messages. Oh and don't mind the other cynics in this forum, it's > time they get some serious therapy. 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. 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.
