> Key: SOLR-9981
> URL: https://issues.apache.org/jira/browse/SOLR-9981
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Houston Putman
> Assignee: Dennis Gove
> Priority: Minor
> Labels: patch
> Fix For: master (7.0)
>
> Attachments: SOLR-9983.patch
>
>
> Included are the following improvements/fixes:
> * Improving the unit test case.
> * Performance fix that stops the reading of ALL lucene segments over and
> again for each stats collector.
> ** The AtomicReaderContext that refers to the "current " segment is reused.
> ** This fix shows an improvement of about 25% in query time for a dataset of
> ~10M (=9.8M) records.
> ** Given the nature of the fix, the improvement should get better as the
> dataset increases.
> * Fix for the NPE during comparison
