Why is Solr query latency increasing?
Queries are taking too long to return with results.
A user asked us to investigate unusual query latency (long waits) during peak traffic periods. Examination of Solr and load-balancer logs in this case showed no significant internal delays.
A test script run at an East Coast data center showed normal latency, but the same script run from a European data center showed latency spikes. The team concluded that, in this case, the problem was network latency between the test client and the deployment. This could be due to routing behavior or how heavily-utilized those network routes become at high-traffic periods.
Solr 5 Query Page
A user reported that a simple query from the Solr 5 UI query form took several minutes to display 1000 documents. The user's browser became unresponsive in the meantime.
This problem was traced to a known bug in the standard Solr 5 UI. The work-around is to click the "new UI" link in the upper right corner of the screen. This shows an "experimental" page where the document display bug has been fixed.
