Cloud-based Load Testing with Visual Studio Online now supports up to 100 cores for a single load test run.
Until now in Cloud-based Load Testing, you could use up to 20 cores (10 agents) in a single load test run. With the support for 100 cores, you should be able to generate 5 times the concurrent users than before. For example, , in a typical single load run using declarative web test, you will be now be able to generate 25,000 concurrent users, where you could generate just 5,000 until now (Of course, if your tests are light you could go well beyond this number). And you can run more than one run in parallel to further get a multiplier effect. You can read more about cores per virtual user and minimum users per core, here.
For leveraging this, you can specify the number of cores you want, in the properties sheet of your ‘Run Settings’ in your load test file. Go to the Run settings->Properties:
Update ‘Agent Count (Total Cores)’ to your desired number (up to 100 cores):
