more than 250 concurrent users for load test

Question

I am using ‘Visual Studio 2010 ultimate’ to automate web based application in order to carry out performance testing. I am aware that there is a limit of 250 concurrent users per client PC.

 

1. Is it possible to run the scripts simulataneoulsy  from 2 PCs in order to create 500 concurrent users or 3 PCs to create 750 concurrent users ?
2. Will that reflect correct performance of the Appliaction?
3. Will this involve further licence purchase of other gadgets ? or is does the MSDN subscription cover them ?

The other alternative will be to use loadrunnner..

Answer 1

Yes, you can run from more than one (1) PC. This link should answer your questions:

Answer 2

Hi,

#1->Yes, you can do that but you won't get a single report to analyze the performance of your application as you'll be running 3 load tests from 3 different boxes. So you'll get 3 reports. Good thing here is to use vUser Pack and run a single load test with 750 vUsers. Also while doing run without vUser only one core of CPU gets used.

#2-> Your application will be put under 750 user load but it will be tough for you to analyze the run data as there will be 3 different runs as I mentioned above.

#3-> No, you need not to buy anything if you want to go ahead with your approach. If you want to do it in right / preferred way then you need to buy vUser  pack. Please read here for more details: http://msdn.microsoft.com/en-us/library/ff426120(v=VS.100).aspx
