Considered removing spring where I work to speed up startup times. Found the biggest bang for the buck was rewriting a bean factory to parallelize singleton preinstantion.

That's what I thought the optimal route was. That's how much we benefit from the strong spring ecosystem.

(It was a little less of a pain than you might think because I didn't have to support all spring features, just the ones we use, which happen to mostly not be features used during singletons preinstantion)
