ASP.NET MVC Performance Tips

Database access is usually the largest performance bottleneck of web applications. But once you’ve optimized and cached your database queries as much as possible here are 3 quick tips that might help you squeeze out a few more requests out of your ASP.NET MVC applications and web servers.
Depending on which features you are using they might not always apply to your application and their benefit will not be that significant (a few % points improvement at most – sorry I don’t have more specific numbers as I’m writing this from memory). I can’t guarantee how much improvement you will see as it depends so much on what your application does. But I hope this will provide some leads for you to investigate. Just remember to always measure for your specific scenario.

Disable unused view engines

When: Your application is using built-in display/editor templates (via the Html.EditorFor or Html.DisplayFor methods) and you are using only one type of view engine.
Why: ASP.NET MVC is generally very good about caching file lookup hits (views, partials, display/editor templates). However one scenario that is not cached is the use of the built-in (default) display/editor templates (where all file lookups are misses).
Any time you use the Html.EditorFor or Html.DisplayFor methods and you do not have a matching template file MVC will generate the appropriate markup for you based on the model’s metadata. However, before that happens it checks all the view engines to find a template file. The more view engines you have registered the longer this will take and since the miss is not cached the process will have to be repeated the next time a page is requested. If you are using only one view engine in your project you should remove the other ones in Global.asax.
