Reading between the lines here: does "full request" return a larger number of documents? How many? Are you attempting to return values for the fields (either implicitly or by glob)? Are you certain that the fields are all `stored=true`? If you're calculating stats on them, they are presumably already `docValues=true`. Do all of the docs contain all of the fields (i.e., you have 5k fields -- does each individual doc have all 5k fields, or a only a subset of the total number of fields)? By any chance, is "QTime" (as reported in solr logs and response body) appear substantially less than the actual amount of time it takes to receive the response in the client?
