Pete Muir commented on WELD-522:
1) This is the bootstrap code for Weld SE (in Weld):
bootstrap.startContainer(Environments.SE, deployment, this.applicationBeanStore);
final BeanDeploymentArchive mainBeanDepArch = deployment.getBeanDeploymentArchives().get(0);
this.manager = bootstrap.getManager(mainBeanDepArch);
I would suggest inserting a line between each of these lines that prints out the time taken for that step as a starting point. Run this two or three times and let us know where the big delays are.
2) We haven't done any performance work specific to Weld SE.
> Weld makes my Java SE app startup time >100x slower
> Key: WELD-522
> URL: https://jira.jboss.org/jira/browse/WELD-522
> Project: Weld
> Issue Type: Bug
> Affects Versions: 1.0.1.Final
> Environment: Java 6, Weld 1.01 SE + lots of jars on the classpath
> Reporter: Morten Christensen
> Booting my Java SE app without weld takes << 1s BUT the 1 line for initializing weld to autowire my app takes at least 4-5 seconds.
> My app is not so big and consist of ~20-30 singletons that must be wired + various other non-weld stuff. I have lots of stuff on my classpath so I suspect that could be why weld is going crazy.
> I guess this could be improved if I can have weld limited to work only inside my own jar and/or only work with specific classes/packages.
> P.S. With breakpoints enabled in a debugger and a bit of unluck, I was even able to have welds initialization to take ~ 5 minutes one day (reduced to seconds again after I removed all breakpoints though).
