[DAX] Best Practices 101 for Optimization & Performance (with Alberto Ferrari)

Despite being usually very fast, DAX can be optimized, like any other computer system. Optimizing DAX requires a deeper understanding of the internals of the engine, because most optimizations are not intuitive. We will talk about the basics of optimizations, looking at some examples of code and discussing together ideas and options to make the code faster.

Unfortunatelly you can give only one thumb up, I would give a hundred!

I don’t think that the “other” time has anything to do with the rendering. It’s wait time in the AS model. 🤷🏼

[@HavensConsulting]

The visual display is the rendering. Sorry if that was misquoted. The other does encompass waiting for other visuals to load though! Here's the quote for that from the MSFT Document Other - This is the time required by the visual for preparing queries, waiting for other visuals to complete, or performing other background processing.
