You skipped the part where you commit and close. If you are optimizing the index down to a low number of segments, that would explain most of the slowdown. Another part is that you open the index for each batch. That takes a bit of time. If you have frequent batch runs, you might want to switch to a setup where the index writer is persistent. - Toke Eskildsen, state and University Library, Denmark --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
