>             Project: Weld
>          Issue Type: Bug
>          Components: Performance and Scalability
>    Affects Versions: 1.0.1.Final
>         Environment: Java 6, Weld 1.01 SE + lots of jars on the classpath

> 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).
