thanks Eric, Well the index was build from scratch with 4.1. Our IT Engineer was able to take some CPU sampler and on analyzing it he mentioned that "While running I noticed that the method: java.util.AbstractList$ltr.hasNext() (called by org.apache.lucene.document.Document.getFields() ) taking a large chunk of CPU time."
I can share the snapshot taken at different interval if required. The confusion is that we have moved the same Index to another VM with virtually same specs and it works fine over there. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr3-5-Vs-Solr4-1-Help-please-tp4043543p4044033.html Sent from the Solr - User mailing list archive at Nabble.com.
