Don't you have any limits for ShardHandlerFactory set in solr.xml? debugQuery=true or debug=track can produce verbose shard request tracing info. Perhaps it might get some clue. Full fledged approach is https://solr.apache.org/guide/solr/latest/deployment-guide/distributed-tracing.html for sure. Might it be a problem of slow dns names resolution? Does it still slow on rows=0? -- Sincerely yours Mikhail Khludnev
