Analyzing full thread dumps will give you the statistical distribution, which is quite accurate if you have enough data. In the full thread dumps I saw so far, I didn't see a thread running within the query engine itself. All (~300) threads where in the LuceneIndex for this case. So I expect the query engine part is negligible (less than 1%). Regards, Thomas
