Fix Query Performance #1
Description
The performance of the query, that aggregates the data is not efficient.

Currently the query is only getting data from the last 3 days, because more would kill the process.
Either the query is improved or we'll find a way to do some intermediate aggregation that is also stored in the DB, that enables faster querying.
