Subject Solr grouping performace
Date Thu, 03 Oct 2013 10:31:16 GMT
Hello ,
I am using solr 4.0 , I want to group entries on one of the int field , I
need all the groups and group.limit is 1. I am getting very slow performance
and some times I am getting OutOfMemory also. 

My index is having 20 million records and out of which my search result
returns 1 million document and I do grouping on these 1 million docs. The
side of data on disk is approx 2GB and I am having Xmx 2GB. Please can
anyone help me out in this. performance is very slow it takes 10-12 seconds.

Thanks ,
