My heap is about 24G an I tuned it using this link https://wiki.apache.org/solr/ShawnHeisey#GC_Tuning_for_Solr
Shawn updated since I use it and some configuration are not in this document any more. I see on my GC logs pauses about 6s, my index has a high index rate > 1000 docs/s. I'm running java 7u25, maybe upgrading to java 8 the GC pauses reduced. I don't know if is safe use java 8 in production with solr ... ----- Best regards -- View this message in context: http://lucene.472066.n3.nabble.com/Too-many-updates-received-since-start-tp4224617p4224631.html Sent from the Solr - User mailing list archive at Nabble.com.
