Hi All, First off, I'm quite the noob when it comes to Nutch, so don't bash me if the following is an enormously stupid question.
We're using Nutch on a P4 Duo Core system (800mhz fsb) with 4gig RAM and a 500gig SATA (3gig/sec) HD. We indexed 350 000 pages into 1 segment of 15gig. Performance is really poor, if we do get search results it will take multiple minutes. When the query is longer we are getting the following: "java.lang.OutOfMemoryError: Java heap memory" What we have tried to improve on this: - Slice the segments into smaller chuncks (max: 50000 url/per seg) - Set io.map.index.skip to 8 - Set indexer.termIndexInterval to 1024 - Cluster with Hadoop (4 nodes to search) Any ideas? Missing information? Please let me know, this is my graduation internship and I would really like to get a good grade ;) -- View this message in context: http://www.nabble.com/Perfomance-problems-and-segmenting-tf3631982.html#a10141310 Sent from the Nutch - Dev mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
