I am currently working on a DocValues performance regression in Solr 7, where one of the symptoms is a lot of read activity (LUCENE-8374). With that in mind, could you tell me * How many documents you have in your index? * Whether you use stored or docValues for the fields that you retrieve as part of the search result? * If you perform heavy faceting, grouping or stats? Maybe provide a sample query, if you are able? Thanks, Toke Eskildsen, Royal Danish Library
