Laurent Almeras commented on HSEARCH-1019:
------------------------------------------

I try your fix this night. Indexation lasts 12 seconds now, so I also notice better performance than with 4.0 and 3.x with your patch.

It's a very good job !

> We need to profile the new mass indexer design and try to reduce the number of index commits. Performance of the filesystem based directory declined to a bug fix in Lucene (https://issues.apache.org/jira/browse/LUCENE-3418). Trying to reduce the amount of index commits (and hence fsync calls) might alleviate the performance loss.
