Prasad created SOLR-5267:
----------------------------
Summary: Solr.xml (persistent=true) - slows down when core
increases beyond 3 - 5K
Key: SOLR-5267
URL: https://issues.apache.org/jira/browse/SOLR-5267
Project: Solr
Issue Type: Bug
Affects Versions: 4.3.1
Reporter: Prasad
The response time of deploying new core increases to 40+ seconds, when
persistent=true is enabled in solr.xml.
The issue seem to be due to iterations over the loop to add all existing cores
and then generated solr.xml
org.apache.solr.core.CoreContainer.addPersistOneCore - calls to this function
need to be optimized.
*Ideas*
* Having only entries for loadOnStartup cores in solr.xml should be sufficient.
* Each core directory can have its properties.
* Transient core lookup can be performed through this file.
* There need a better way to track the all registered core (than XML).
