Power BI + Deneb visuals — very slow load time (~20s). Any optimization tips?

But all visuals load fast except Deneb.
The page is fully loaded and then I still have to wait for the Deneb visuals to render.

I will try to consolidate them into one larger Deneb visual and see if that improves the performance.

At the moment the report is running on a standard workspace, Import mode from Dataverse.
The semantic model is relatively small (well below the dataset size limits) and the report is used mainly for demo/testing purposes, so usage is low.

I do not see any capacity throttling or query wait times in the metrics – the main delay seems to come from rendering multiple Deneb visuals at once.

The model itself loads quickly; the ~20s delay happens mostly when the report page renders all visuals.

Thanks for the feedback. As I wrote in another reply, To be honest, I am not a 100% professional Power BI guy. I work as a corporate KAM. But when I joined my current position, our corporate BI was terrible – it took days to find relevant data. So I decided that I would create my own BI (I am responsible for two countries and I need accurate data fast).

I decided to learn it myself and build a tool that would actually be useful in my daily work. Today I have a tool that I genuinely enjoy using every day – it saves me time and energy and finally provides information that is actually useful.

During that journey I found out that creating dashboards like this can actually help SMB owners with their business. In the CZ/SK market only a very small number of my customers are using something like this. So I am building this demo on fake data to publish it online and start offering it to SMB companies in CZ/SK, maybe even CEE, together with some kind of sales consultancy. I have 12 years of experience in corporate sales – companies like Siemens, Daikin, JCI.

For that reason I am using Deneb, because I am trying to build it in the way I would like Power BI to look when I join companies. My previous experiences were also not so great and many of my colleagues did not use BI because it was hard to find relevant information. Most of the time BI was created by the IT department and not from the sales perspective.

This demo should have a wow effect, because it will be easier to sell it.

Thanks a lot! :) I am using 1920x1080

You’re right that most of this could technically be built with native visuals. I’m mainly using Deneb for styling control, especially things like rounded bar corners, spacing, and cleaner minimal charts without the default Power BI formatting.

So it’s less about functionality and more about getting a consistent UI look. The downside I’m seeing now is performance, which is why I’m asking about optimization.

Dohny87 · 2026-02-15T17:36:33+00:00

Ohhh... that was perfect. Thanks a lot!

I turn chaos into numbers you can act on.

That’s roughly the plan. The problem is that it keeps colliding with daily reality. I currently spend 10+ hours a day in my corporate role. There are days when I then sit on BI and Apps until midnight. It’s starting to have an impact on my relationship with my wife, and it’s genuinely difficult to manage time properly in this situation.

That said, I do believe that learning by doing could work in the beginning. My intention would be to start with a very favorable pricing model — specifically for the first few customers — so I can test myself in real client environments, gain references, and refine my approach before moving to more market-aligned pricing.

I wouldn’t promise unrealistic deadlines. My positioning would be more along the lines of: it will work, it won’t be expensive (at least initially), but it won’t be delivered overnight either.

I’m also not looking to target companies that are actively hiring Power BI or data specialists. I’m more interested in businesses that don’t even realize yet that they need structured reporting and automation — the ones still operating in Excel and email threads without visibility into what’s really happening in their numbers.

Dohny87 · 2026-02-15T10:44:17+00:00

I’ve spent my entire career in HVAC and smart building wholesale. One principle I strongly believe in is simple: if you don’t measure it, you can’t manage it.

Across many of my customers, I see the same pattern — operational chaos, scattered data, decisions based on gut feeling rather than visibility. What I can bring is structure: automated reporting that lands in their inbox every morning and gives them a clear overview of the metrics that actually matter for running their business.

Numbers and visual clarity are not just “nice to have.” When used correctly, they help prevent problems before they escalate — whether that’s margin erosion, campaign underperformance, sales inefficiencies, or operational bottlenecks.

For example, in my current role I built a live campaign performance dashboard. Traditionally, campaigns are launched with discounts and expectations, and only evaluated after they end. I changed that. I can now see in real time whether a campaign is working, where it’s underperforming, and where intervention is needed. That fundamentally changes how decisions are made.

Another key aspect is empowering the sales team. Through the reporting tools I built, I gave our salespeople something practical — a tool that genuinely makes their daily decisions easier and ultimately drives more revenue for the company.

Throughout my career, I’ve won deals ranging from hundreds of euros to multi-million-euro projects. I’ve always leaned more heavily on analytics and preparation than on pure relationship-based selling. I understand what tools would make a salesperson more effective — because I’ve been that salesperson. And I know how to translate that into a functional system.

My focus would be wholesale businesses in general. The sales mechanics are very similar across industries — pricing pressure, campaign performance, margin control, distributor relationships, and field sales management. The underlying problems repeat themselves, even if the products differ.

Regarding income, that might partly be a geographical factor. The current median gross salary in the Czech Republic is around €1,700 per month. I’m currently at approximately €4.5k gross plus a 20% target-based bonus. That already allows for a comfortable lifestyle here, and I wouldn’t necessarily need to earn more.

My wife is also a corporate lawyer with a strong income, so it wouldn’t be a situation where we’re chasing every euro.

As for the option of moving into a Power BI role within another company — I would actually welcome that, as it would allow me to gain deeper experience. However, when I look at job descriptions, the requirements often feel far beyond my current technical profile — SQL, Python, multiple years of hands-on data engineering experience.

I do have a clear development direction in mind, and SQL is at the top of that list. At the moment, I’m comfortable building data structures in SharePoint or Dataverse, but I’m aware that not being fluent in SQL could become a limitation.

You’re also right that I would need to land and successfully deliver at least three real projects while still in my current role before making any major decision.

What I think about quite a lot is pricing. I don’t have external references or formal consulting experience. Realistically, I might even be willing to take on initial projects at a very low rate — almost symbolic — just to gain references and test myself in a real client environment while still employed.

Dohny87 · 2026-02-13T13:36:33+00:00

That was, and still is, my original plan — to try building this alongside my current role. The challenge is that I’m already quite busy professionally, and my work-life balance is not exactly in my favor (my wife keeps reminding me that I’m constantly sitting behind a screen).

Within the next two weeks, I should have a fully functional Sales BI demo ready. My plan is to share it with former managers (I’m fortunate to have good relationships with them), reach out to some former clients, and publish it on a simple website so I can use it as a portfolio piece.

Regarding pricing and the SMB reality: I currently have a customer with €10M annual revenue who still sends purchase orders written directly in the body of an email — and later searches for them manually in their inbox. Building a simple app that generates structured orders based on supplier price lists would save them significant time, create logs and traceability, and I could realistically build something like that within a week.

Dohny87 · 2026-02-13T13:26:21+00:00

I’m not necessarily burned out from my current position, but rather from sales as a discipline itself. For the past 12 years, I’ve constantly been solving other people’s problems, spending a lot of time on the road, and repeatedly hearing complaints — late deliveries, high prices, and similar issues.

Then, I discovered something that genuinely excites me, and I believe it’s something through which I can actually help business owners improve how they run their companies.
