----------------------------------
Summary: Disable Stale Check - Distributed Search (Performance)
Key: SOLR-4509
URL: https://issues.apache.org/jira/browse/SOLR-4509
Project: Solr
Issue Type: Improvement
Components: search
Environment: 5 node SmartOS cluster (all nodes living in same global
zone - i.e. same physical machine)
Reporter: Ryan Zezeski
Priority: Minor
By disabling the Apache HTTP Client stale check I've witnessed a 2-4x increase
in throughput and reduction of over 100ms. This patch was made in the context
of a project I'm leading, called Yokozuna, which relies on distributed search.
Here's the patch on Yokozuna: https://github.com/rzezeski/yokozuna/pull/26
Here's a write-up I did on my findings:

I'm happy to answer any questions or make changes to the patch to make it
acceptable.
