Load tests contain scenarios, which contain Web performance tests. Scenarios are important because they give you flexibility in configuring test characteristics that allow for simulation of complex, realistic workloads. You can have more than one scenario per load test. Use the Load pattern, test mix model and test mix to specify what webtests to use, the manner in which the load will be applied to your application and pacing. You can also use Browser mix, Network mix to make your workload more realistic.
Counter sets that are useful when you analyze performance counter data. The counter sets are organized by technology such as Application,. You can create counter sets during the initial New Load Test Wizard or later on the load test file itself. There is a set of predefined counter sets or you can create your own. You can also add counters to the default Counter Sets or to your own. The counters are added from Perfmon. Visual studio will collect data for every counter on a set for each computer where it is mapped to.
Run settings are properties that organize the manner in which a load test runs. You can have more than one run setting in a load test but only one can be active at a time while the other settings provide a quick way to select an alternative settings. Settings are used to specify things like test duration, Logging, SQL server collection, warm up duration, sampling rate or validation setting between others.
Check this article for full description of tasks available. Make sure your Load test is configure to run On premises by checking the General section of your active. Test Settings are not the same as Run Settings. Other items to configure on this window are Roles and Timeouts. That dialog should show if the controller has any Test Agents connected to it. More information here: Manage Test Controllers. From that point forward you should be ready to run a Load Test. During or after run time you have access to Graphs and Tables with throughput, response times information, performance counters for the computers you configured and details on vusers activity.
Check this tutorial to learn more: Run and analyze your load test. Visual Studio offers extendibility options to increase the built-in functionality.
Follow the articles below to learn more about the different options:. Please feel free to ask questions in the Comments section of this blog post. I can try to answer them and add them to this FAQ. As mentioned above the recommendation is up to for a 2. This can change depending on the length of the webtests, the payloads of the application responses and the use of custom plug-ins. The client Visual Studio machine uses a random port by default which is used to receive the test results from the test controller.
For all incoming connections, the test controller authenticates the calling party and verifies that it belongs to specific security group. This is true regardless of the test rig configuration you are using: on premises or cloud based testing:.

In this unit, you’re configuring only the debug configuration and setting it to use a release build of CPython. This condition can occur if you create a source file without a. For example, if you accidentally entered module. Such misidentification remains even if you rename the file with a. To set the file type properly, in Solution Explorer , right-click the file and select Properties.
You’ll find the. If you haven’t already done so, repeat the preceding steps to create a second project named superfastcode2 with an identical configuration. Then, add a function that exports the module, along with definitions of the module’s methods. The sections that follow explain how you perform these steps by using both the CPython extensions and PyBind Be sure to select your version of Python in the dropdown list at the upper right.
Add a structure that defines the module as you want to refer to it in your Python code, specifically when you use the from That is, it matches the file name of the.
If you come across errors, see the “Troubleshooting” section. For more information about the code in this section, see PyBind11 basics. Install PyBind11 by using pip: pip install pybind11 or py -m pip install pybind Alternatively, you can install PyBind11 by using the Python Environments window, and then use its Open in PowerShell command for the next step.
In the same terminal, run python -m pybind11 –includes or py -m pybind11 –includes. Be sure to remove the -I prefix, if it’s present. At the top of a fresh module. At the bottom of module. If you encounter errors, see the next section, “Troubleshoot compiling failures,” for solutions.
Error: Unable to locate Python. Now that you have the DLLs structured as Python extensions, you can refer to them from the Python project, import the modules, and use their methods. You can make the DLL available to Python in any of several ways. Here are two approaches to consider:. Do the following:. In the dialog that appears, select the Projects tab, select both the superfastcode and superfastcode2 projects, and then select OK.
An alternative method installs the module in your Python environment, which makes the module available to other Python projects as well. For more information, see the setuptools project documentation. Create a file named setup. Naming the file with the. When the file appears in the editor, paste the following code into it, as appropriate to the extension method:.
Create a second file named pyproject. To build the extension, right-click the open pyproject. You’ll delete the pyproject. If you’ve already installed the package, you’ll see it listed here. Before you continue, click the X to uninstall it.
In the search box, paste the copied path, delete pyproject. If the installation fails because of a permission error, add –user to the end, and try the command again. After you’ve made the DLL available to Python, as described in the preceding section, you can call the superfastcode.
To call the DLL, do the following:. Add the following lines in your. Typical output appears as follows:. Feel free to switch between those configurations for comparison, but remember to go back and update the properties that you set earlier for the release configuration. In the output, you might see that the PyBind11 extension isn’t as fast as the CPython extension, though it should be faster than the pure Python implementation. PyBind11 generates slightly more complex code to provide a more Python-like interface to callers.
But, because the test code calls the function , times, the results might greatly amplify that overhead! You could reduce the overhead further by moving the for loop into the native code. This approach involves using the iterator protocol or the PyBind11 py::iterable type for the function parameter to process each element. If you receive an ImportError message when you try to import your module, you can resolve it in one of the following ways:.
Ensure that your output file is named superfastcode. Any other name or extension will prevent it from being imported.
