-------------------------------
Summary: Query response time severily regressed when upgraded Jena
TDB to 2.11.2 from 0.9.4
Key: JENA-800
URL: https://issues.apache.org/jira/browse/JENA-800
Project: Apache Jena
Issue Type: Bug
Components: ARQ, TDB
Affects Versions: Jena 2.11.2
Reporter: Bala Kolla
Many queries, that used to take few milliseconds in 0.9.4, are now taking
minutes.
Here is one of the query that's taking few minutes instead of few milliseconds.
I will capture the algebra before and after and update this issue once I have
that data.
