I did some profile testing with the new ConjuctionScorer in 2.1 and discovered a new bottleneck in ConjunctionScorer.sortScorers. The java.utils.Arrays.sort method is cloning the Scorers array on every sort,
Huh... that's interesting. I wonder why Arrays.sort(int[]) is all in-place but sort(Object[]) is not.
which is quite expensive on large indexes because of the size of the 'norms' array within, and isn't necessary. We rewrote this to use simple insertion sorting
The code looks more like a bubble sort to me. Anyway, conjunctions will normally not have many scorers I think so this should be OK. Can you open a JIRA issue for this? -Yonik http://incubator.apache.org/solr Solr, the open-source Lucene search server --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
