Eran, What version of Lucene are you using? Are you opening the IndexReader in read-only mode?

When closing the reader, the indexing speed goes back to normal. I'm not doing any deletes, only adds. My index is going to be updated regularly and there's going to be a reader/searcher in use almost all the time so this might be a big problem for me. Does anyone have a clue if this is normal behavior? why does it happen and how can I avoid such a big loss in performance? Thanks, Eran.
