Power BI Performance & DAX Optimization
Fix slow reports and overloaded capacity: DAX audit, semantic-model refactor, aggregation and Direct Lake tuning, with before/after proof.
Overview
Slow reports, refreshes that fail overnight and a capacity that pegs at 100% are not a reason to buy a bigger SKU — they are usually a modelling problem. This package audits your DAX and semantic models, refactors what is slowing them down, tunes aggregations and the Import / DirectQuery / Direct Lake strategy, and proves the result against a recorded baseline.
Scope scales from a single report or model audit, through a departmental semantic-model refactor, to enterprise-wide capacity optimization — every engagement ends with a results-parity check, a capacity before/after report and a handover so your team keeps the gains.
What you get
- Bottleneck analysis with baseline timings (Performance Analyzer / DAX Studio)
- Optimized measures and calculation groups
- Model optimization (relationships, data types, aggregations, Import/DirectQuery/Direct Lake strategy)
- Capacity (CU) consumption before/after report
- Results-parity verification against baseline
- Performance maintenance guide and team handover session
