> Project: OpenWebBeans
> Issue Type: Improvement
> Components: Context and Scopes
> Reporter: Vladimir Dvorak
> Priority: Minor

> Class javax.enterprise.inject.spi.BeanManager generates a lot of full lookups
> (tens of thousands) in InjectionResolver.implResolveByType() when OWB is
> starting even in simple project. It looks that OWB starts could be improved
> by 10-20% by introducing caching. I'm trying to put cache in BeanImpl as is
> shown there:

> it skips expensive iteration over all beans and improves start of OWB, in my
> case from 10.5s to 9.9s. Probably there is better way how to do it, since the
> problem is only with the class javax.enterprise.inject.spi.BeanManager.
