Fix Slow Power BI Reports with Australia's Performance Specialists
Slow, crashing or unreliable Power BI reports don't just frustrate your team - they erode trust in the numbers and stall every decision waiting on them. Report Simple is Australia's specialist Power BI performance optimisation team. We audit your DAX, data model, refreshes and capacity, hand you a prioritised fix list within five days, and then make the fixes - so reports that took minutes to load respond in seconds, and your executives stop making decisions on stale data.
Measured, Not Guessed
Every bottleneck is benchmarked with Performance Analyzer and DAX Studio before we touch anything, so fixes target proven causes rather than hunches.
Fix List in 5 Days
Our fixed-fee health check delivers a prioritised fix list within five business days, ranked by speed impact and effort so you approve only what pays off.
Same Numbers, Faster
Side-by-side validation guarantees every optimised measure reconciles exactly with the original - your reports get faster while the results stay identical.
Lower Capacity Costs
Leaner models and tuned refreshes frequently let clients run on a smaller Premium or Fabric capacity, turning the optimisation into an ongoing saving.
Zero Disruption
Your team keeps working in their reports throughout - changes are version-controlled, staged through your workspaces and instantly reversible.

Power BI Performance Audit & Health Check
Find out exactly why your reports are slow - in days, not months. Our fixed-fee health check analyses your worst-performing reports using Performance Analyzer, DAX Studio and capacity metrics, tracing every delay to its root cause across visuals, measures, the data model and refresh pipeline. You receive a prioritised fix list ranked by impact and effort, so you know precisely where the speed is hiding before committing to any remediation work.
DAX Optimisation & Measure Tuning
Rewrite the measures that are silently strangling your reports. Inefficient DAX is the most common cause of slow visuals - iterator-heavy calculations, misused filter context and measures that scan entire tables for a single number. Our specialists rewrite your heaviest measures for the storage engine rather than against it, often turning thirty-second visuals into sub-second responses without changing a single result.
Data Model Restructuring
Fix the foundation that every visual depends on. Flat, wide tables, snowflaked relationships, unnecessary columns and bi-directional filters force Power BI to work far harder than it should. We restructure your model into a clean star schema, trim what the report never uses, and shrink model sizes dramatically - which speeds up everything at once: visuals, refreshes and development.
Refresh & Capacity Optimisation
End the failed refreshes and capacity warnings. We tune your refresh strategy with incremental refresh, query folding and sensible scheduling, and analyse your Premium or Fabric capacity metrics to stop noisy reports starving the rest of the tenant. The result is data that lands on time every morning - often on a smaller, cheaper capacity than you are paying for today.
Report Rescue & Ongoing Monitoring
Keep reports fast after we leave. Beyond one-off rescues of broken or abandoned reports, we establish performance standards, set up usage and capacity monitoring, and document the patterns your team should follow - so the next dashboard your analysts build starts fast and stays fast.

TRUSTED BY
Our Proven Power BI Performance Optimisation Process
Our senior specialists diagnose the real causes of slow reports, fix them in priority order, and prove every gain with before-and-after measurements.
1
Five-Point Performance Audit
We benchmark your slowest reports across the five layers where performance hides: visuals, DAX measures, the data model, refresh pipeline and capacity. Using Performance Analyzer and DAX Studio we capture hard timings for every bottleneck - no guesswork, no opinions, just measured evidence of exactly what is slow and why.
Prioritised Fix List in 5 Days
2
Within five business days you receive a plain-English report ranking every issue by speed impact and effort to fix - from five-minute setting changes to deeper model restructuring. Each item includes the measured time cost and the expected gain, so you can approve the high-value fixes first and skip anything that isn't worth the spend.
Optimisation Sprint & Validation
3
Our specialists implement the approved fixes in a controlled sprint, validating every change side-by-side against the original so totals never shift. You receive before-and-after benchmarks proving the gains, updated documentation, and the performance standards your team needs to keep new reports fast from day one.

Power BI Performance Optimisation FAQs
Why is my Power BI report so slow?
Slow Power BI reports are almost always caused by one of five issues: inefficient DAX measures, a poorly structured data model, too many visuals on a page, an overloaded refresh pipeline, or an undersized capacity. In our audits the most common culprits are:
Heavy DAX: iterator functions and misused filter context scanning millions of rows per visual.
Flat data models: wide tables and bi-directional relationships that multiply the work behind every click.
Oversized models: columns and history the report never uses, bloating memory and refresh times.
Crowded pages: dozens of visuals each firing their own queries on every interaction.
The good news: these are all fixable without rebuilding from scratch. Our audit pinpoints which ones are costing you the most time - request a health check to find out.
How much does a Power BI performance audit cost?
Our fixed-fee Power BI performance health check starts from $2,500 to $5,000 depending on the number of reports audited, with the optimisation work that follows typically ranging from $5,000 to $15,000. Because the audit produces a fix list ranked by impact and effort, you control exactly how much remediation to approve - many clients capture the majority of the speed gains from the top three or four items alone. Specialist Australian rates sit around $200 to $250+ per hour, but we quote both the audit and the sprint as fixed fees so there are no surprises.
For a quote based on your report count and model sizes, request a performance audit.
How long does Power BI performance optimisation take?
The audit takes five business days, and most optimisation sprints complete within one to three weeks after that. Typical timelines:
Health check (5 days): Benchmarks, root-cause analysis and your prioritised fix list.
Quick wins (week 1): Settings, visual reduction and the worst DAX offenders - often where the most dramatic gains land.
Structural fixes (weeks 2-3): Model restructuring, incremental refresh and capacity tuning.
Reports stay live throughout - every change is validated side-by-side before it replaces the original.
How much faster will my Power BI reports get?
It depends entirely on what the audit finds - which is exactly why we measure first and promise second. That said, the pattern across our engagements is consistent: reports suffering from heavy DAX or flat data models routinely go from thirty-plus seconds per click to one or two, and bloated models often shrink by more than half, speeding up refreshes and development at the same time. Where a report is already well built and the constraint is genuinely capacity or data volume, we will tell you that honestly - and recommend the right next step instead, whether that's incremental refresh, a capacity change or Direct Lake on Fabric.
Every engagement ends with before-and-after benchmarks, so the gains are proven, not promised.
Will optimisation change my report's numbers or disrupt my team?
No - performance optimisation changes how your numbers are calculated, never what they equal, and your team keeps using their reports throughout. Our process is built around that guarantee:
Side-by-side validation: every rewritten measure and restructured table is reconciled against the original before it goes live.
Version control: originals are preserved, so any change can be rolled back instantly.
Staged releases: fixes deploy through your normal workspace process, not as a big-bang replacement.
If the audit reveals a report that genuinely needs rebuilding rather than tuning, we'll say so - that work is handled by our dashboard development team with the same validation discipline.
