Pre-Loading Schema Topic IDs

One aspect of the schema that greatly affects the application initialization time is time spent retrieving the unique TMCore topic IDs that correspond to subject identifiers in the map. With a complex schema, it may take over 100 web service invocations to build a map caching subject identifier to topic ID.

Fortunately this process can be mitigated by using the NetworkedPlanet.EPiServerModule.IdentityHelper.PreloadTopicIDs(string) method. This method causes the module to precache the topic IDs of any topics that have a subject identifier that match the parameter passed to this method. You can call PreloadTopicIDs at any point after the web application has initialized, for example you have add a call during Application_Start in global.asax.cs as shown here:

protected void Application_Start(Object sender, EventArgs e)

{

  development.Templates.Wsrp.Core.ProducerBaseSupport.InitializePortlets();

  IdentityHelper.PreloadTopicIDs("http://www.networkedplanet.com/psi/%");   // Preload all topic IDs where subject ID starts with the pattern shown

}
