What is measure optimization best practice?

< 1 min read

Measure optimization best practice means writing efficient DAX that minimizes memory and CPU usage.
Use variables (VAR) to store intermediate results and avoid repeated calculations.
Prefer aggregated calculations over row-by-row iterators like SUMX on large tables.
Avoid high-cardinality functions like DISTINCTCOUNT unless necessary.
Keep measures simple and reusable rather than nesting multiple complex measures.
Leverage existing relationships and filter context instead of applying heavy FILTER functions.
Test performance using Performance Analyzer to identify slow measures.
Overall, optimized measures improve report responsiveness and reduce refresh time.
