It is slow
Pages take many seconds to load, filters lag, or the refresh runs long or fails. People stop opening it.
- page load
- refresh time
- timeouts
I audit the model, fix what is slow or wrong, and document the result, so the report stops being one person's secret.
If one of these sounds familiar, the others are probably close behind.

Two reports show two totals for the same thing. Finance has its own version. Nobody can say which one is right.
The original builder left, or is the only one who knows how it works. Every change feels risky.
Nobody can say for sure who can see what. Sharing was set up one request at a time.
These are the problems I find most often. I measure first, so I fix what is actually slow and not what looks suspicious.
You see the findings and the plan before any change is made.
I review the data model, the DAX measures, the refresh setup, and the report pages. I measure load and refresh times so we have a baseline.
You get a list ordered by impact: what is wrong, what it costs you, and what fixing it takes. You approve before I change anything. If a rebuild is cheaper than a repair, I say so.
I make the approved fixes and check the numbers against your source. Then I document how it works, so the next person can pick it up.
Usually a few causes, not hundreds. The common ones are listed above. Measuring first, with Power BI's own performance tools, shows which ones apply to your report.
Often, yes. Most slow reports have a handful of problems that account for most of the delay. I rank them by impact. If a rebuild would be cheaper and safer, I tell you that instead.
No. You approve the fix list first, and I work from that list.
I measure load times and refresh duration before and after, and give you both numbers.
I need access to the workspace and the model. I ask for more only if a specific fix requires it, and I tell you why.
Yes. That is most of this work: reports built by a former employee, an agency, or a team that has since moved on.
If I cannot improve it, I will tell you that straight, before you spend more on it.
Tell me what you're working with and who needs to see it. If I can help, I'll tell you how. If I can't, I'll tell you that straight.
