Spring Projects Issues

**[Chris Beams](https://jira.spring.io/secure/ViewProfile.jspa?name=cbeams)** commented Niklas, 2h 30m is a very long time indeed, but again, I would encourage a more pragmatic approach. For the majority of Spring applications, container startup time...

**[Niklas Schlimm](https://jira.spring.io/secure/ViewProfile.jspa?name=niklas)** commented Hi Chris, understand your view point. Thanks for the comprehensive reply. Cheers, Niklas

**[Adib Saikali](https://jira.spring.io/secure/ViewProfile.jspa?name=asaikali)** commented I think parallel startup of Spring is very important, in my application spring is taking up 50% of my startup time, reducing that would be very helpful...

**[Ragnar Rova](https://jira.spring.io/secure/ViewProfile.jspa?name=rrva)** commented Please see https://github.com/gredler/spriths for an experimental example implementation. Seems like the spriths implementation goes far into making it work. The author of spriths mentions #10033 that needs...

**[Scott Murphy](https://jira.spring.io/secure/ViewProfile.jspa?name=scottland)** commented Is this worth revisiting now that it is 2 years later?

**[Scott Murphy](https://jira.spring.io/secure/ViewProfile.jspa?name=scottland)** commented "Users are free to reopen this issue" Maybe keep this issue open so it can be voted upon?

**[Adib Saikali](https://jira.spring.io/secure/ViewProfile.jspa?name=asaikali)** commented I think this problem has two distinct parts parallel discovery of beans and parallel initialization of beans. Both of which can be implemented separately to improve performance...

**[Julien Dubois](https://jira.spring.io/secure/ViewProfile.jspa?name=jdubois)** commented Start-up performance is a very important issue to me, and I think a lot of beans could be initialized in parallel. So yes this issue should stay...
