When I try to start up tomcat in debug mode (via myeclipse tomcat plugin) on a struts/hibernate application, the initialization of Hibernate sessions goes from 4 seconds to 3.5 minutes. We created a struts plug in that initializes the hibernate configuration upon startup. The log file indicates that the longest amount of time occurs when configuring the ehcache. Here are some times from my log file:

With debug:
2006-05-19 10:04:35,577 WARN net.sf.ehcache.config.Configurator: No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: file:/C:/apache/Tomcat_5_0/webapps/tams/WEB-INF/classes/ehcache-failsafe.xml
2006-05-19 10:04:38,009 INFO org.hibernate.impl.SessionFactoryObjectFactory: Not binding factory to JNDI, no JNDI name configured

Without debug:
2006-05-19 10:53:51,057 WARN net.sf.ehcache.config.Configurator: No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: file:/C:/apache/Tomcat_5_0/webapps/tams/WEB-INF/classes/ehcache-failsafe.xml
2006-05-19 10:53:54,018 INFO org.apache.struts.tiles.TilesPlugin: Tiles definition factory loaded for module ''.

Hibernate version: 3.1.2

Name and version of the database you are using: Oracle 10g

Is this difference in time between debug and not debug normal? That's a long time to wait so I turned off running in debug mode but at some point, I'll want to turn it back on. At that point, I'll be making lots of changes to code and will have to restart the application multiple times. Is there a way to speed things up in debug mode?

Thanks,

A colleague and I are developing with hibernate 3.2 on tomcat 5.5.17, using Eclipse 3.2.1 and MyEclipse 5.0GA and MySQL 5.0.18. We use the same project source in a subversion repository.

My machine starts in 10s in run mode and 16s in debug mode.
His (newer) one takes 5s in run mode and 90s in debug mode.
We can't work out why his is so much slower in debug mode.

We've traced through the tomcat console output on each machine, and they are identical.

His tomcat slows down just after this line:
INFO [org.springframework.beans.factory.support.DefaultListableBeanFactory] - <Pre-instantiating singletons in factory [org.springframework.beans.factory.support.DefaultListableBeanFactory defining beans [xxDao, yyDao, ...]; parent: org.springframework.beans.factory.support.DefaultListableBeanFactory defining beans [dataSource,jmxExporter,statisticsBean,sessionFactory]; root of BeanFactory hierarchy]>

There are delays in initialising the servlet, but there are further delays in getting tomcat started after that:

I'd appreciate any tips for how to isolate the differences between the two machines.

Review your IDE's debug breakpoints and make sure that you aren't evaluating any breakpoint conditions. Depending on your IDE, this evaluation can slow things down considerably.

Mubbled - thanks! It made a huge difference. Deleted all 5 breakpoints, and now it starts in 10s.
Interestingly, putting breakpoints back doesn't seem to slow it down so much, but we're much happier now.
Thanks again.

John.

please feel free to recommend the post and drop us a credit :)

Would if I could, but I think I can't do that because I didn't start the thread. I don't see any buttons. If I'm wrong, please tell me how.
