Parameter file configuration

For running the script in Controller/Performance Center always use data file as unique on each iteration in parameter setting. Generally we select parameter file sequential on each iteration which is not a good practice, this option will force all users to pick the first value of parameter list.

e.g:

if there are 100 users and we have 100 data in parameter file, when we select sequential on each iteration then all the 100 users will pick the first data and then in second iteration they will take the second data. If the data is unique and can be used by only one user at a time then our script will fail. However when we run the same script in VUgen then it will pass.

We can use another method to validate the data in VUgen itself rather than running it in Controller. Use blocks in Run Time setting and keep init and end part in action and run it for 100 iteration. In this case on every iteration it will take the new data from parameter file. But this is not a good practice as every time the user will log out and login.

Pacing Time in LoadRunner

What is Pacing? Where and why to use it? -Pacing is the time which will hold/pause the script before it goes to next iteration. i.e Once the   Action   iteration is completed the script will wait for the specific time(pacing time) before it starts the next one. It works between two actions. eg, if we record a script there will be three default actions generated by the Load Runner:   vuser_init, Action   and   vuser_end,   the pacing will work after the   Action   block and hold the script before it goes to repeat it. The default blocks generated by LoadRunner is shown below: Actions marked in Red Now we know what is pacing and we use it between two iteration. The next question comes to mind is why we use pacing: Pacing is used to: To control the number of TPS generated by an user. To control number of hits on a application under test.     Types of Pacing: There are three options to control the pac...

How to troubleshoot high Memory utilization during performance testing

 When troubleshooting high memory utilization during performance testing, it's important to identify the underlying causes and take appropriate steps to address the issue.  Here are some steps to troubleshoot high memory utilization: Monitor Memory Usage: Use performance monitoring tools to track memory usage over time. Monitor both physical and virtual memory (RAM) to identify if memory consumption is exceeding available resources. Identify Memory-Intensive Processes: Identify the specific processes or components that are consuming a significant amount of memory. Performance monitoring tools can help you identify the memory-hungry processes. Look for any particular application, service, or module that stands out in terms of memory usage. Analyze Code and Memory Allocation: Review your application's code and algorithms to identify any memory leaks, inefficient memory allocation, or excessive object creation. Look for areas where large amounts of memory are being consumed unnec...
