Shinichiro Abe created SOLR-6889: ------------------------------------ Summary: debug, highlight with parallel streams Key: SOLR-6889 URL: https://issues.apache.org/jira/browse/SOLR-6889 Project: Solr Issue Type: Improvement Affects Versions: Trunk Reporter: Shinichiro Abe
I think we could gain search performance a little bit using Stream.parallel().forEach()~ which has processors awareness via f/j framework under the hood. Especially it would affect docList's for-loop processes, e.g. debugging, highlighting. It seems to me that this improvement is effective for many CPUs environment. My test condition: 1. Core i5(2core 4thead), standalone Solr. 2. q=日本&debug=true&hl=true, other parameters are [here|https://github.com/anond2/simplesearch/blob/master/conf/solrconfig.xml#L836]. 3. 7171 hits / 12000 docs(taken from ja.wikipedia dump) 4. compared to trunk, parallel streams are faster a little.
