MG updated HHH-2867:
--------------------
Attachment: ReflectionTest.java
Ok, let me try again...
It does 5000000 invocations in each run
in Run4 using cglib FastClass.invoke
in Run5 using javassist FastClass.invoke
Run5 takes significantly more time.
Run4 time=94ms
vs
Run5 time=17547ms
Which leads me to believe that javassist reflection optimization would be slower than
cglib.
Please, check it yourself by running the code from attachment
Anyway this bug report really is about
hibernate.bytecode.provider=cglib
being completely ignored in in hibernate.properties
Thanks
HIbernate reflection optimization with javassist MUCH slower than in
previous versions with cglib

Key: HHH-2867
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2867
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.3
Reporter: MG
Attachments: ReflectionTest.java
Hibernate reflection optimization with javassist MUCH slower than in previous versions
with cglib,
and there is no way to set it to use cglib anymore
I'm setting
hibernate.bytecode.provider=cglib
in hibernate.properties
but it is still using javassist
[java] 10:42:00,675 INFO [Version] Hibernate Annotations 3.2.1.GA
[java] 10:42:00,722 INFO [Environment] Hibernate 3.2.3
[java] 10:42:00,737 INFO [Environment] loaded properties from resource

[java] 10:42:00,737 INFO [Environment] Bytecode provider name : javassist

Please, check sample code in
http://jira.jboss.com/jira/browse/JBSEAM-1977
which compares cglib with javassist optimizations
cglib beats JDK 5 reflection almost 10 times
javassist performs even slower than JDK 5 reflection
