Ah, i was almost lead to believe this issue was addressed :)
The work-around is fine, but with the whole analysis and processing inside Solr
nowadays, i'd expect more users could run into this. I, at least, have no idea
how to address this and post a patch.

> Key: SOLR-7580
> URL: https://issues.apache.org/jira/browse/SOLR-7580
> Project: Solr
> Issue Type: Improvement
> Affects Versions: 5.1
> Reporter: Markus Jelsma
> Fix For: 5.5, 6.0
>
>
> We have several batch jobs that use StreamingResponseCallback to collect all
> records matching a specific query. For each record, we execute a new query
> and need all results without paging through them. Because we do not know the
> amount of matches to expect, we do setRows(Integer.MAX_VALUE);. According to
> the VisualVM samples, this results in a huge amount of ScoreDoc instances,
> making the query unreasonably slow.
> The current work-around we use is to execute the same query with setRows(0),
> get numResults, and then reissue the query with setRows(numResults). This is
> fast, almost as fast as one would expect.
> This is, however, a very dirty work-around. I am unsure whether this is a
> Solr or Lucene issue, SolrIndexSearcher is a beast to debug ;)
