Common DAX Performance Issues

Reports taking 30+ seconds to load
Measures that work in simple reports but fail at scale
CALCULATE with complex filter contexts causing errors
Time intelligence broken with non-standard calendars
Circular dependency errors in complex models
Memory consumption exceeding capacity limits

If any of these sound familiar, our DAX experts can help.

DAX Optimization Services

From quick performance fixes to complete DAX rewrites, we cover the full spectrum of optimization.

Performance Audits

We analyze your DAX measures using DAX Studio and Performance Analyzer to identify bottlenecks, unnecessary calculations, and optimization opportunities.

Query Optimization

Rewrite inefficient DAX patterns, eliminate iterator abuse, optimize CALCULATE filters, and reduce storage engine pressure.

Time Intelligence

Implement robust YTD, QTD, MTD, rolling averages, same period last year, and fiscal calendar calculations.

Calculation Groups

Replace repetitive measure variants with calculation groups for time intelligence, currency conversion, and dynamic formatting.

Advanced Patterns

Virtual relationships, dynamic segmentation, parent-child hierarchies, many-to-many patterns, and semi-additive measures.

Model Optimization

Column data type optimization, relationship tuning, aggregation tables, and DirectQuery/Import hybrid strategies.

Essential DAX Patterns

Must-know DAX patterns for every Power BI developer.

Time Intelligence Patterns

Implement robust time intelligence with DAX best practices.

Frequently Asked Questions

How do you identify DAX performance issues?
We use DAX Studio to capture query plans and server timings, Performance Analyzer in Power BI Desktop, and VertiPaq Analyzer to examine model statistics. This reveals exactly which measures are slow and why.
How much faster can you make our reports?
Most optimizations achieve 5-20x improvement. We have seen reports go from 30+ seconds to under 2 seconds by fixing iterator patterns, removing unnecessary CALCULATE contexts, and optimizing data models.
Can you optimize DAX in DirectQuery mode?
Yes, DirectQuery DAX optimization is different from Import mode. We focus on query folding, reducing round-trips, implementing aggregation tables, and writing DAX that translates efficiently to SQL.
Do you provide DAX training for our team?
Yes, we offer hands-on DAX training from fundamentals to advanced patterns. Training includes real-world examples from your data and custom exercises based on your reporting needs.
