I tried the serialization and deserialization and WOW it has shorten the startup a lot, By the way I'm developing a desktop application that's why the startup thing matters to me.
How do you guys measure the duration of these operations in seconds and miliseconds, I'm curios to know, do you use any open source tools? or you just get the time before the method call and after and calculate the difference. Anyway thank you for your fast replies, I hope this is discussion is going to be useful for somebody else like me. visar On Mar 30, 10:33 pm, Fabio Maulo <[email protected]> wrote: > Deserialization is faster > > FNH : 04.360 > ConfORM : 00.958 (with hibernate.cfg.xml) > Deserialization: 00.283 > > Time in second measured to have a full configured configuration ready to > BuildSessionFactory > > 2010/3/30 Ajai Shankar <[email protected]> > > > > > > > Out of curiosity, in the grand scheme of things what difference does > > shaving maybe a couple of seconds? on startup make... > > > Ajai > > > On Tue, Mar 30, 2010 at 3:11 PM, Fabio Maulo <[email protected]> wrote: > > >> we are going to check how much faster is the configuration-deserialization > >> over add-Xml-Deserialized > > >> 2010/3/30 Ricardo Peres <[email protected]> > > >>> Visar, > > >>> In order to fasten startup time, you can serialize the Configuration > >>> object: > > >>> Configuration cfg = new Configuration().Configure(); > >>> IFormatter serializer = new BinaryFormatter(); > > >>> using (Stream stream = File.OpenWrite("Configuration.serialized")) > >>> { > >>> serializer.Serialize(stream, configuration); > >>> } > > >>> ... > > >>> using (Stream stream = File.OpenRead("Configuration.serialized")) > >>> { > >>> cfg = serializer.Deserialize(stream) as Configuration; > >>> } > > >>> RP > > >>> On Mar 30, 7:04 pm, Fabio Maulo <[email protected]> wrote: > >>> > The life cycle of the mapping is explained herehttp:// > >>> fabiomaulo.blogspot.com/2010/03/nhibernate-mappings-path.html > > >>> > 2010/3/30 Fabio Maulo <[email protected]> > > >>> > > The third... > >>> > > After BuildSessionFatory all mapping-metadata are compiled to > >>> persisters > >>> > > and you can throw the Configuration with its state. > > >>> > > 2010/3/30 Diego Mijelshon <[email protected]> > > >>> > > Fabio answered he first part, so I'll answer the second one: > > >>> > >> "Is the impact on performance only in startup?
