Can you please suggest how to configure for a Load Test of 100 transactions

How to configure Arrivalrate in for 100 transactions or do we need to configure any other things, please suggest.
Here is the situation we are planning to test run 4 classes into 100 Transactions, I have configured the arrivalRate for 5 concurrent users for each class

Test case specific load configuration

com.xceptance.xlt.loadtests.TVisit.users = 5
com.xceptance.xlt.loadtests.TVisit.arrivalRate = 25

com.xceptance.xlt.loadtests.TBrowse.users = 5
com.xceptance.xlt.loadtests.TBrowse.arrivalRate = 25

com.xceptance.xlt.loadtests.TSearch.users = 5
com.xceptance.xlt.loadtests.TSearch.arrivalRate = 25

com.xceptance.xlt.loadtests.TAddToCart.users = 5
com.xceptance.xlt.loadtests.TAddToCart.arrivalRate = 25

Here in test run, not able to run the users simultaneously, refer to the image

Here in the report getting only 11 transactions, refer to the image below:

Thanks in advance!

The arrival rate is per hour and the users might not run all the time because when you spread 25 visit across an hour, there are many gaps with nobody doing anything. So when you test runs 1h, you will see about 100 transactions (assuming you have had an rampup as part of that time).

See the documentation:

Hope that helps.
