Kira Traynor commented on SOLR-16758: ------------------------------------- Thanks for the response! I've attached the patch to the ticket that I applied and did testing on to get the difference in query latencies. I wanted to get some concrete examples that I could actually share with a valid test and that you could reproduce. To test, I created local instances of solr (one with the current version of solr and the other with the patch) and indexed 2 million documents and was comparing the results with the following query: {code:java} {!graph from=node_s to=edge_ss maxDepth=1 v='*:*'}{code} In the patch I included a performance test within org.apache.solr.search.join called testGraphQueryPerformance(). The createGraphIndex() method generates a test index with an id, a node, and an edge value to be able to be queried with the graph query. To create the index on the local instances of solr, I generated documents using the same method. Running performance tests against the local instances of solr, I found that the changes to the graph query produced distinct differences (on average ~20% faster). > GraphQuery Performing Slower in Solr 9 > -------------------------------------- > > Key: SOLR-16758 > URL: https://issues.apache.org/jira/browse/SOLR-16758 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
