Ryan Zezeski commented on SOLR-4509: ------------------------------------ > ...i'll be testing this in the next few days. Great, I would love to see these results reproduced by someone else. > I'm not very sure enabling TCP_NODELAY (e.g. disable Nagle's algorithm) will > help a lot I agree, it probably doesn't matter but I disabled it anyways given that nagle is really meant for things like telnet and such. I figured it couldn't hurt to disable. > 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 > Attachments: SOLR-4509.patch > > > By disabling the Apache HTTP Client stale check I've witnessed a 2-4x > increase in throughput and reduction of over 100ms.
