Speeding Up NHibernate Startup Time

One technique I use and posted on the NHUsers mailing list consists in serializing a previously-configured Configuration to the filesystem and deserializing it on all subsequente starts of the application:

Configuration cfg = null;
IFormatter serializer = new BinaryFormatter();

//first time
cfg = new Configuration().Configure();

using (Stream stream = File.OpenWrite("Configuration.serialized"))
{
	serializer.Serialize(stream, configuration);
}

//other times
using (Stream stream = File.OpenRead("Configuration.serialized"))
{
	cfg = serializer.Deserialize(stream) as Configuration;
} 

Check it out for yourselves.

Update: Fabio Maulo posted about this some time ago on NHForge. You can find his post here.
