in Solr's admin statistics page, there is a 'current' flag indicating whether the core index reader is 'current' or not. According to some discussions in this mailing list a few months back, it wouldn't affect anything. But my observation is completely different. When the current flag was not checked for some of the cores ( I have defined 15 cores in total), my median search latency over 48M records was over 190ms, but if every current flag was checked, the median dropped to only 87 ms.
Another observation is, restarting solr instance may not necessarily make 'current' flags checked, have to reload cores even after starting solr. Could anybody explain the difference? I am using Datastax Enterprise 3.0.2 Thanks, -- View this message in context: http://lucene.472066.n3.nabble.com/Perf-difference-when-the-solr-core-is-current-or-not-current-tp4074438.html Sent from the Solr - User mailing list archive at Nabble.com.
