Hi Uwe: First, thanks very much!
I have two questions ! 1> When the field cache will create? 2> I find the theads always block! In our system, solr only process 6.4788313 req/second! And in my solr stats.jsp : *name: *fieldCache *class: *org.apache.solr.search.SolrFieldCacheMBean * version: *1.0 *description: *Provides introspection of the Lucene FieldCache, this is **NOT** a cache that is managed by Solr. *stats: *entries_count : 4 entry#0 : 'org.apache.lucene.store.niofsdirectory$niofsindexin...@ca0045'=>'releasetime',class org.apache.lucene.search.FieldCache$StringIndex,null=>org.apache.lucene.search.FieldCache$StringIndex#6161693 entry#1 : 'org.apache.lucene.store.niofsdirectory$niofsindexin...@ca0045'=>'modifytime',class org.apache.lucene.search.FieldCache$StringIndex,null=>org.apache.lucene.search.FieldCache$StringIndex#10601874 entry#2 : 'org.apache.lucene.store.niofsdirectory$niofsindexin...@ca0045'=>'id',class org.apache.lucene.search.FieldCache$StringIndex,null=>org.apache.lucene.search.FieldCache$StringIndex#11665632 entry#3 : 'org.apache.lucene.store.niofsdirectory$niofsindexin...@ca0045'=>'source',class org.apache.lucene.search.FieldCache$StringIndex,null=>org.apache.lucene.search.FieldCache$StringIndex#5735666 insanity_count : 0 2010/7/20 Uwe Schindler <[email protected]> > Hi Jason, > > > > Where is exactly the problem?
