bq. the searchtime was around 300 ms whereas the same query without the code
changes
BTW this doesn't apply to the first search. The first search is *slow*, but by
configuring query listeners the first user wouldn't notice.

> This issue is dedicated to the performance of the grouping functionality.
> I've noticed that the code is not really performing on large indexes. Doing a
> search (q=*:*) with grouping on an index from around 5M documents took around
> one second on my local development machine. We had to support grouping on an
> index that holds around 50M documents per machine, so we made some changes
> and were able to happily serve that amount of documents. Patch will follow
> soon.
