Gregory Chanan resolved LUCENE-7115. ------------------------------------ Resolution: Fixed Fix Version/s: 6.1 trunk Thanks for the review, Mark, committed to trunk and 6.1 > Speed up FieldCache.CacheEntry toString by setting initial StringBuilder > capacity > --------------------------------------------------------------------------------- > > Key: LUCENE-7115 > URL: https://issues.apache.org/jira/browse/LUCENE-7115 > Project: Lucene - Core > Issue Type: Improvement > Components: core/search > Reporter: Gregory Chanan > Assignee: Gregory Chanan > Fix For: trunk, 6.1 > > Attachments: LUCENE-7115.patch > > > Solr can end up printing a lot of these objects via the JmxMonitoriedMap, see > SOLR-8869 and SOLR-6747 as examples. > From looking at some profiles, a lot of time and memory are spent resizing > the StringBuilder, which doesn't set the initial capacity. > On my cluster, the strings are a bit over 200 chars; I set the initial > capacity to 250 and ran tests calling toString 1000 times. Tests > consistently show 10-15% improvement when setting the initial capacity. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
