Performance of different web application framework

<h2>Background</h2>

<p>Just to find out what's the performance of each web application framework</p>

<h2>What to do?</h2>

<div class="wp-block-image">
  <figure class="aligncenter size-large"><img src="/assets/posts/12/image-3.png" alt="" class="wp-image-310" /></figure>
</div>

<ol>
  <li>A test application will bombard the web application with 100 requests at the same time.</li>
  <li>Token-server is written in various framework.</li>
  <li>Token-server will perform a HTTP call to another backend server.</li>
  <li>Identity-server will perform a fake sleep for 5 secs.</li>
</ol>

<h2>What are the framework used?</h2>

<ol>
  <li>
    Web app will use
    <ol>
      <li>Java 11 + Spring Boot WebMVC 2.3.4</li>
      <li>Java 11 + Micronaut 1.0.3</li>
      <li>Kotlin + Spring Boot Webflux 2.3.4</li>
      <li>NodeJS 12.16.1 + Express 4.17.1</li>
      <li>NodeJS 12.16.1 + Restify 8.5.1</li>
      <li>.NET Core 3.1.300 + ASP .NET Core 3.1.2</li>
    </ol>
  </li>
  <li>Test app will use Java 11 console application</li>
  <li>Another server will use Jave 11 Spring Boot WebMVC 2.3.4</li>
</ol>

<h2>Result</h2>

<div class="wp-block-image">
  <figure class="aligncenter size-large"><img src="/assets/posts/12/image-2.png" alt="" class="wp-image-308" /></figure>
</div>

<ol>
  <li>
    Spring Boot WebMVC is the slowest. Not surprise here because it's the only framework that use thread per request
    model here. It won't work well in the above scenario.
  </li>
  <li>Spring Boot Webflux and Micronaut works better than NodeJS. That's a surprise.</li>
  <li>
    .NET Core is the fastest. This test is done on a Windows machine. Not sure if the it will be the same on Linux
    machine.
  </li>
</ol>

<h2>Notes</h2>

<p>The test might be different on your machine. The full source code is here: https://github.com/chimin/webapp-perf</p>
