Recently, searching our index is becoming slow *after* performing an optimize. This is counter intuitive as usually the optimize has the opposite effect! We're using lucene.net 2.3.2 and have an index of 250,000 documents and about 500 queries per minute at peak times. Performance is good (even after much indexing) until the optimize runs. Then, queries are slow (2-5 seconds) for about 15 minutes until eventually settling down a bit. But in this time, many query threads time out (as we queue when we have to). We are not using any explicit caching methods. Any help/suggestions on what to do would be much appreciated! I'm about to rebuild the index from scratch to see if this temporarily resolves the problem...
