jpountz commented on issue #595: Load freqs lazily in Postings
URL: https://github.com/apache/lucene-solr/pull/595#issuecomment-507545472
 
 
   I wouldn't trust wikimedium10k and wikimedium500k, these collections are small and there is a lot of noise. wikimedium10m suggests we have a good speedup for conjunctions but a slow down for sloppy phrases (span near and ordered intervals queries are a form of sloppy phrases).
   
   Would you be able to re-run the wikimedium10m benchmark, but with changes to `BlockPostingsEnum` and `EverythingEnum` reverted? Said otherwise, only `BlockDocsEnum` and `BlockImpactsEverythingEnum` would read frequencies lazily. I believe this should help address the slowdown we are seeing with phrases while still getting speedups for conjunctions.
