Hello,
I found a temporary solution to my problem. I do a request without ngroups=true => result is quickly And just after, I do a simple request with my query and this param: .&json.facet={x:"unique(fid)"} Where the field « fid » is my group field name. 88 sec => 3~4 sec for both requests.

Hi All, I have more than 130 million documents, with an index size of more than 400GB on Solr8.7. I do a simple query and it takes around 1400ms, its ok but when I use ngroups=true, I get an answer in 88sec. I know its because Solr calculates the number of groups on a specific field but is exist a solution to improve that? An alternate solution?
