iScrollView performance

[Jochem Pouwels]

Hi,
I have been testing iScrollView on my iPhone 5 for a while now. It works great.
But now I have tested it on a iPhone 4 and the framerate is very low when scrolling!

Any tips on how to up the performance?

my erb file looks like this:

<div id="id" data-role="page"data-add-back-btn="true"  >
<div data-id="header" data-position="fixed" data-role="header" data-tap-toggle="false" data-transition="none">
  <center><h1>TITLE</h1></center>
</div>
<% if System::get_property('platform') == 'APPLE' %>
   <div data-role="content" data-iscroll>
<% else %>
   <div  data-role="content">
<% end %>
<div class="providerwrapper">
   <center> something </center>
   <hr>
   <div class="providers">
      <% @providers.each do |provider| %>
      <div class="provider">
         <a href="<%= url_for :action => :index_post, :query => {:provider_id => provider.id}%>">
              <img src="/public/images/provider/<%= provider.img_url %>" style='max-width: 100%; height: auto;'>
         </a>
      </div>
   </div>
   <%end%>
</div>
</div>
</div>
