other[SOLR-1972] Need additional query stats in admin interface - median, 95th and 99th percentile - ASF Jira464 wordsscore: 0.75This is a JIRA issue tracking the implementation of enhanced query statistics in Apache Solr's admin interface, specifically adding percentile metrics (median, 95th, 99th percentile) for request times. The issue was resolved in Solr 4.1/6.0 and led to the integration of the Metrics library for more comprehensive performance monitoring.
troubleshootingjava - Solr search query time increases as the start keeps on increasing - Stack Overflow744 wordsscore: 0.65A Stack Overflow discussion about Solr query performance degradation with deep paging (high start values). The thread addresses the 'Deep Paging' problem where query response times increase significantly when retrieving results with high offset values (e.g., start=100000), and suggests solutions including filter queries and Solr 4.7+ cursor-based pagination.
troubleshootingsettimeout - Timeout Solr search - Stack Overflow509 wordsscore: 0.62A Stack Overflow question about implementing query timeouts in Apache Solr using the timeAllowed parameter. The discussion covers configuration approaches including setting the parameter in solrConfig.xml and via URL query parameters, with clarification that the value must be specified in milliseconds.

CPU Saturation Masking Simple Query Performancewarning
Simple, inexpensive queries (e.g., single-term searches) become slow when CPU is saturated by other operations like indexing spikes, causing queries that should complete in <100ms to take 400ms+.
