Hi Fuad, Thanks for your suggestions and quick response. I am using a single-threaded indexing way to add docs. I will try the multiple-threaded indexing to see if my issue will be resolved.
This issue only exists after I upgraded lucene version from 2.4.1(with Java 1.6) to 4.8.1(with Java 1.7). I don't have this problem in old lucene version. The indexing speed is fast when i start the application, which only takes 3 mins indexing. But after my application running for a while(a day, etc), once i send a JMX call to my application to reindex docs, the indexing speed will slow down and take 22 mins. Did you have any similar experience like the above before?
