How do you compare the DI implementations in both Spring and Guice ? Is there any substantial difference(s) in performance ? Since Guice primarily focuses on DI is it better than Spring's counterpart ?
In performance, a speed test we wrote outdid spring 1.0 by 100x and spring 2.5 by 10x (This benchmark is available in the Guice code repository). Both continue to make speed improvements.

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
