title: xamarin.forms shell tabbar is very slow
body: <p>I'm using the shell tab bar for navigation in my application.
  In the beginning, it worked perfectly, but when my application grew - it started to work slowly.</p>
  <p>Is there an opportunity to solve the problem?</p>
  <p>Here is my shell:</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot; ?&gt;
  &lt;Shell xmlns=&quot;http://xamarin.com/schemas/2014/forms&quot;
         xmlns:x=&quot;http://schemas.microsoft.com/winfx/2009/xaml&quot;
         xmlns:views=&quot;clr-namespace:Anime.Views&quot;
         x:Class=&quot;Anime.Views.ShellView&quot;
         Shell.NavBarIsVisible=&quot;False&quot;
         StyleClass=&quot;shellStyle&quot;&gt;
      &lt;TabBar &gt;
          &lt;Tab Icon=&quot;ic_home.png&quot;&gt;
              &lt;ShellContent ContentTemplate=&quot;{DataTemplate views:HomeView}&quot;/&gt;
          &lt;/Tab&gt;
          &lt;Tab Icon=&quot;ic_search.png&quot;&gt;
              &lt;ShellContent ContentTemplate=&quot;{DataTemplate views:SearchView}&quot;/&gt;
          &lt;/Tab&gt;
          &lt;Tab Icon=&quot;ic_person.png&quot;&gt;
              &lt;ShellContent ContentTemplate=&quot;{DataTemplate views:ProfileView}&quot;/&gt;
          &lt;/Tab&gt;
      &lt;/TabBar&gt;
  &lt;/Shell&gt;
  </code></pre>
