The test in which we got the 11X speedup? That was single threaded. I haven't yet found a way to make multithreaded (shared IndexWriter) indexing perform with any better speed than singlethreaded, so that code is not enabled in our tests. Do you think that 2.3 would better take advantage of multiple threads / cores? If so, I could rerun it again multithreaded and see if that's even better...
