Thanks a lot Nyall, setting the NoGeometry flags and subset of fields does
improve the speed by factor 3 for my test layer ( 300k features and 80 (!)
fields )

Hi all,
I needed to gather basic stats for a layer containing multiple fields. I
created the following gist to compute the number of features per each
unique value for a list of given fields
https://gist.github.com/mdouchin/a234efb7e67ebd8dae3a04cb26cf5e72
I know I could use PostgreSQL to do it
