Hi all,

I'm currently running an umbraco v 4.7.0 website using razor.

The initial page call after an app recycle for different types of pages (homepage / list overview / detail pages ) varies from 3 -> 8 ! seconds when nothing is cached (umbraco macro caching). The second call goes much smoother with a response time of minus 1 second. 

Is this response time a known issue when using razor ? It seems like loading a macro is acting very slow ? 

Since this website is deployed on a shared hosting, the app pool is recycled on a regular base. I'm not allowed to change this config or configure asp.net 4.0 prewarm triggers. 

Using a ping service is could avoid the app pool to recycle but I would prefer fixing this problem without relying on a thirdparty service.

Render time without cache (from tracing):

Code sample Top banners:

@using umbraco.MacroEngines;
@using umbraco.cms.businesslogic.media;
@inherits umbraco.MacroEngines.DynamicNodeContext
@if (Model.HasProperty("banner") && Model.Media("banner") != null)
{
    var image = @Model.Media("banner");
    <img src='@image.UmbracoFile' alt='@image.Name' />
}
else
{
    Media startMedia = new Media(1060);
    Media randomItem  = startMedia.Children.OrderBy(T => Guid.NewGuid()).FirstOrDefault();
    if (randomItem != null)
    {       
        <img src='@randomItem.getProperty("umbracoFile").Value'  />
    }
}

Thanks in advance,
