It's hard to believe that an upgrade from 3.0.3 to 3.4.0 would make that much difference to CPU usage. Are you sure nothing else has changed? Has the crawling/indexing elapsed time gone up in the same proportion? Have you verified that the increased usage is actually in lucene rather than elsewhere?
