why individual parts of render take less 1ms total views rendering on 2 seconds?

home.html.erb: - emptied out see if in here cuaisng slowness outputting single word total view render on 2 seconds.

blah 

_svg.html.erb:

<svg role="img" aria-labelledby="title desc" class="<%= classs if local_assigns[:classs] %>">   <% if local_assigns[:title] %>     <title id="title"><%= title %></title>   <% end %>   <% if local_assigns[:description] %>     <desc id="desc"><%= description %></desc>   <% end %>   <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#<%= hash %>"></use> </svg> 

_banner-slideshow.html.erb:

<div class="gallery banner banner--slideshow">   <div class="gallery__slide"></div>   <div class="gallery__slide"></div>   <div class="gallery__slide"></div>   <div class="gallery__slide"></div> </div> 

_flash-messages.html.erb:

<% if flash.any? %>   <% flash.each |type, message| %>     <%= render partial: 'shared/flash_message', locals: { type: type, message: message } %>   <% end %> <% end %> 

_flash-message.html.erb:

<div class="message-box message-box--<%= type %>">   <a class="close" data-dismiss="alert">×</a>   <%= message %> </div> 

you can improve code reduce call's subviews in _flash-messages.html.erb:

<% if flash.any? %>         <%= render partial: 'shared/flash_message', locals: { flash: flash } %> <% end %> 

then in _flash-message.html.erb:

<% flash.each |type, message| %>   <div class="message-box message-box--<%= type %>">     <a class="close" data-dismiss="alert">×</a>     <%= message %>   </div> <% end %> 

this reduce sub-views rendering , take less time finish job.
