------------------------------------------

Hi Guillaume,
thank you very much, this feedback is very welcome.
I'll start looking into it and will push snapshots for you to try out as soon as I have some good ideas, but it will take some days.. maybe a good Christmas present but it seems unlikely, hopefully before the end of year since we have a short break.

> 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.
