ASF subversion and git services commented on LUCENE-10517: ---------------------------------------------------------- Commit 26d015301df60096f9e61260311da65df51d3a3c in lucene's branch refs/heads/branch_9x from Chris Hegarty [ https://gitbox.apache.org/repos/asf?p=lucene.git;h=26d015301df ] LUCENE-10517: Improve performance of SortedSetDV faceting by iterating on class types (#812) > Improve performance of SortedSetDV faceting by iterating on class types > ----------------------------------------------------------------------- > > Key: LUCENE-10517 > URL: https://issues.apache.org/jira/browse/LUCENE-10517 > Project: Lucene - Core > Issue Type: Improvement > Components: core/index > Affects Versions: 9.1 > Reporter: Chris Hegarty > Priority: Minor > Time Spent: 1h 10m > Remaining Estimate: 0h > > While analysing various profiles, [@grcevski|https://github.com/grcevski] and > I can came across this potential improvement. > SortedSetDV faceting (and friends), can improve performance within tight > loops by using invokevirtual (rather than invokeinterface). The C2 JIT > compiler can produce slightly more optimal code in this case, and since these > loops are very hot, the impact can be significant (in the order of 10-30%). > This issue is in some ways similar to, and builds upon, prior optimisations > in this area, like say LUCENE-5300 or more recently LUCENE-5309 -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
