title: require vendor/autoload taking 14 seconds
body: <p>In our development teams, a decision has been made to not use composer (Not sure why yet). So whenever we want to use a package from 3rd party, we just use composer but copy and paste the files manually into our workspace. So in other words, we never deploy our application using <code>composer install</code> or <code>composer update</code>. Now I have installed a package called pusher using  <code>composer require pusher/pusher-php-server</code></p>
  <p>My issue is that I'm not sure how to use the files since there is no composer autoload. My only solution was to require the autoload <code>include EXTENSIONS_PATH.'/pusher/vendor/autoload.php';</code></p>
  <p>However I found that whenever I call the file that includes the autoload, it takes around 14 seconds to load.
  We are using php with yii.</p>
  <p>Another solution was to use this at the beginning of the application</p>
  <pre><code>Yii::registerAutoloader(
          function () {
                  require_once EXTENSIONS_PATH.'/pusher/vendor/autoload.php';
          }
  );
  </code></pre>
  <p>Using the above made it work in 200ms, however it conflicted with google API package that was installed in a similar manner and using similar Guzzle dependencies but with versions. If I put that piece of code just before I want to use pusher, the same 14 seconds happens.</p>
  <p>Any help is appreciated. This is driving me crazy, and please do not close the question.</p>
