Performance Check With MiniProfiler In ASP.NET MVC

• If you get an error after running the application with MiniProfiler.Mvc4 or MiniProfiler.Mvc3, which states “/mini-profiler-resources/includes.js 404 not found”, then simply add the following line of code in Web.Config inside Web Server section.
  
  1. <system.webServer>
  2. <handlers>
  3. <add name="MiniProfiler" path="mini-profiler-resources/*"
  4. verb="*" type="System.Web.Routing.UrlRoutingModule"
  5. resourceType="Unspecified" preCondition="integratedMode" />
  6. </handlers>
  7. </system.webServer>

Finally, we have done all the installation and settings to configure MiniProfiler with ASP.NET MVC application. Now, we can run the application. To run, press F5 and the application will be populated as follows with MiniProfiler Data at the top left corner of the application. The output will be like in the below image. Here, we can see clearly how much time each event has taken to process.

If we view the “page source”, we will find the following scripting code which is auto generated and added with the View to display the profiling data.

Now, let us move on to see how MiniProfiler works with actual data. To complete this demonstration, we are going to create some dummy blog post data in one step and in the next step we are going to modify the actual username.

Note

I am creating dummy data inside the controller itself. Instead of this, we can get actual data from API.

We can define our own steps to see which process takes how much time. So, basically, STEPs in MiniProfiler are used to see the performance of each process, like getting data from the server, updating data on the server or posting data in Database etc. Here I am going to create a list for Blog Posts and define it inside one STEP. Another STEP will be defined to update the Username for Blog Post as in the below code shown.

So, first, let's create a model class for a blog post which has a few properties to define the blog data. Just create a class inside the Model folder with the name “BlogPost”.

Now, move to the home controller and define steps. The first step will be defined to“Get Blog Post Data”. Here, we are creating dummy details for the blog post to show on View but instead of this, we can also get the actual data from our services or APIs. With the next step “Update User Info”, we are modifying the username based on a certain condition. Once the Model is defined, it will be passed to View to render the data on the View in a tabular format.

It's time to render the data on Index.cshtml View. So, make iteration on Model data and fill in the table as below.

Now, we have set up the steps, let's run the application to see what happens. If we run the application, we will see the output as following where we can see the actual data in Table format along with profiling data created by MiniProfiler.

We can clearly see the STEPs [Blue Circled with Image] which we have defined at the time of creating dummy data “Get Blog Post Data” and “Update User Info”. Here, we can see how much time this application has taken to “Get Blog Post Data” and how much time is consumed to “Update User Info”.

So, based on this profiling report, we can modify our logic so that our application will get, post, update, or delete the data in minimal time.

Conclusion

Thus, we saw how to implement MiniProfiler with ASP.NET MVC application and how it can help us to know the actual time taken by each process.
