[jira] [Commented] (OAK-2199) Capture performance stats for lucene property indexes

["Amit Jain (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-2199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14173421#comment-14173421 ] 

Amit Jain commented on OAK-2199:
--------------------------------

The updated numbers are on a windows system with 16GB RAM.
The test run was {{AggregateNodeSearcher}}. The tests were run with the patch installed [OAK-2005-fixes.patch|https://issues.apache.org/jira/secure/attachment/12674920/OAK-2005-fixes.patch]. With the 1st change needed for producing results and the 2nd change needed for index selection.

|*Indexing (Random data)*|*Time Seconds (2.6 m nodes)*|*Time Seconds (5.25 m nodes)*|
|OrderedIndex|3540|>30 hrs|
|Lucene|878|1847|
For insertions the indexing time is way better than ordered indexes with an almost linear relationship to the data.

Query times are somewhat better than above
|*Query*|*Time Seconds (2.6 m nodes)*|*Time Seconds (5.25 m nodes)*|
|OrderedIndex|0.5|NA|
|Lucene|2.5|3.4|

I enabled benchmark profiler for the query and following is the output which indicates lot of time spent on reading blobs from FDS.
