Re: [Hibernate] Startup time

[Michael Gloegl]

Hi all,

here are some quick shot results using hprof (I'll do some more detailed 
examination as soon as I have OptimizeIt access again):

For testing, I did a simple SessionFactory building on all the mappings 
from the Unit tests. (except 4). In the default configuration, the rough 
approximation is:

Of the time spent for the whole session factory building:

1/6th is spent for cglib.proxy.Enhancer.create (via 
CGLIBProxyFactory.postInstantiate)

1/7th is spent on cglib.beans.BulkBean.create and 
cglib.reflect.FastClass.create

This both happens in the call hierarchy of 
PersisterFactory.createClassPersister, which accounts to roughly half of 
the startup time (so mostly reflection and cglib here)

1/3rd of the total startup time goes to Configuration.addInputStream, 
nearly completely to dom4j.io.SaxReader.read

These are only preliminary results, I hope to post some more detailed 
numbers soon, with different cglib settings etc.

Michael
