Results grouping performance with groups.ngroups=true
Hi,
The time taken to group results when the resultset has ~ 200k items is very high.
Is there a way to optimize the performance.
The group count and facet count is required.
Regards,
Sayan

I mean, you might probably count the same counts by json facet *instead*
slow grouping count, like

Hi Mikhail
Even after using json facets latency seems to be high if group.ngroups=true.

As far as I remember, groups facets can be calculated with json.facets a
way faster.
