Spring framework question

Question

Spring is well used these days. Are there any deficiencies of spring. Can it handle very heavy load?

Answer 1

I believe it can, but Google didn't bring back any citations to back up that claim.

I don't think that Spring would be the deciding factor in web app performance under a heavy load. The app server and its configuration, the design of the application, etc. would have as much or more influence than the Spring framework.
