I really like the idea of the new Data Preparation capabilities in QS 3.0. The performance is really a problem.
When I point to a relational source, I want to be able to look at the relationships and the data quickly. To do this is Qlik Sense, is very slow. Just a database with a few tables and a couple of 100,000 rows takes several minutes wait while it grads the and prepares it.
Is anyone else having a similar experience?
