[jira] [Commented] (DELTASPIKE-1161) [perf] avoid Instance#Select

    [ https://issues.apache.org/jira/browse/DELTASPIKE-1161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15312936#comment-15312936 ] 

Romain Manni-Bucau commented on DELTASPIKE-1161:
------------------------------------------------

[~tandraschko] not so sure about the context but select can be cached (the new Instance until it gets unambiguous) and @Inject can be used with @Dependent relying on Provider. It will require runtime resolution and instantiation but we can ensure we do it cleverly I guess.

> - Instance#select: 46119ms
> - BeanProvider: 42231ms

> @Inject will break dependent-scoped but there is currently not real-world usecase 
> We could however introduce a config in the future
