The "SolrPerformanceData" page has been changed by ivansmall. http://wiki.apache.org/solr/SolrPerformanceData?action=diff&rev1=16&rev2=17 -------------------------------------------------- On our production index, the average Solr response time is around 200 ms, median response time 90 ms, 90th percentile about 450 ms, and 99th percentile about 1.4 seconds. Details on the hardware are available at [[http://www.hathitrust.org/blogs/large-scale-search/new-hardware-searching-5-million-volumes-full-text|New hardware for searching 5 million plus volumes]] Some details on performance are available at: [[http://www.hathitrust.org/blogs/large-scale-search/performance-5-million-volumes|Performance at 5 million volumes]]. Background and updates available at:[[http://www.hathitrust.org/blogs/large-scale-search|The HathiTrust Large Scale Search blog]] + == Zvents == + + [[http://www.zvents.com|Zvents]] serves more than 8 millions users monthly with engaging local content. We've used Solr for several years and have achieved very high performance and reliability. User queries are served by a cluster of 8 machines, each having 16Gigs of memory and 4 cores. Our search index contains over 4 million documents. An average week day sees a maximum 80qps with an average latency of 40ms. Leading up to New Years, we'll see ten times this level. To support huge fluctuations in our capacity needs, we run a nightly load test against a single production class machine. The load test itself uses Jmeter, a copy of production access logs, and a copy of the production index. The load testing machine is subjected to 130qps and delivers an average latency of 150ms. +
