Profile mass indexer to reduce number of index commits

Description

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.
