Thanks for reply, but unfortunatelly it's not helpfull at all.

I can use google myself and I already read those before I posted this question.

 

I'm looking for an answer to question why OData feed is much slower then downloading the data manually and using them as JSON source. Is it doing some validation against model which is time consuming or what?

 

Anyway even then the performance is terrible. Somebody with experience could tell if it's even worth a try to optimize this. Is our approach - download all and filter in Power BI, wrong for our data model? Is direct query - where we will filter data serverside based on user selected parameters better approach for this case?

 

Regards,

Michal

      Hi,

      Unfortunatelly no.

      PowerBI is not cappable of processing high-volume OData payloads effeciently. If your endpoint supports filtering and projections ($filter, $select), you can apply those operators by yourself and import result into PowerBI as plain JSON.
