The invisible problem slowing down your business - it's called IT performance ...

When is software fast enough? A serious question to which every organization should have only one answer. Because . we are now 100% dependent on digital processes. Even your physical processes - from production to logistics, from customer contact to invoicing - run on the digital backbone of your organization. And that digital world determines not only whether your business runs, but also how fast. How fast your employees can work. How quickly your customers are served. How quickly you can respond to new opportunities.

That's why good IT performance is no longer a luxury, but an absolute basic need.

Yet many organizations blindly assume that the software they buy or (have built) will "perform well. That performance is a tick box that the vendor automatically includes. But that usually turns out to be an expensive assumption.

Because what is good performance? When is fast enough? And: will that performance - that accepted speed - hold up when your organization grows, when your usage changes or when your software is used more intensively than originally thought?

In practice, performance is often the blind spot. Systems that are slow, applications that falter or wait times that increase are often accepted - “that's just the way it works” - while the damage to productivity, customer experience and costs can be substantial. To be clear, “that's just the way it works” are often the words of the vendor; the IT organization sighs and looks for the solution to "how to do it better.

In this blog, we explain:

• what good performance actually is

• why a lot of modern software does not live up to it

• how to discover if your systems are slowing down your organization

• and what is needed to get and keep performance structurally in order

Because if performance turns out to be your bottleneck, optimization is no longer an IT project - but a growth accelerator. And that will make you happy!

The wind chill factor of software: the infamous 3-second limit

Once again that question: when is software “fast enough”? The answer is simple and merciless: when the user does not notice any slowdown. And that limit is much lower than we all think.

Some time ago, UX research revealed that our brains work with the powers of 10 - time intervals at which users' behavior and attention fundamentally change:

• 0,1 secondd: feels like instantaneous. The user does not notice a delay. Anything below this threshold is experienced as instant response.
• 1 second: still feels fast, but the user notices a slight delay. The system no longer feels “instant,” but it does feel smooth.
• 3 seconds: this is the critical limit. Wait longer than this? Then the user becomes distracted. Attention wanes. Doesn't fit the powers of 10, but it is a proven critical limit. Note: for millennials and Generation Z, this limit is as low as 2 seconds.
• 10 seconds: the user mentally drops out. They look away, grab their phone or click on something else.
• 1 minute: with these kinds of waiting times, the interaction is actually broken. Think timeouts, reloads, or leaving the process completely.

And these numbers are not just some UX babble. The list above applies to all software with direct user interaction: portals, web apps, mobile apps, workplace software.

Why this is important?

Because much modern software - especially in the cloud - greatly exceeds these thresholds. That happens with 100% certainty when you scale, use more data or address multiple systems simultaneously.

Three seconds seems short, but to a user it is an eternity.

Are you making users wait longer than that? Then you lose not only attention, but also productivity, customer satisfaction and ultimately money.

So performance doesn't start with 99.9% uptime. It starts with how fast your software is and therefore feels. And whether that speed is enough to keep people in the right flow.

Slow, expensive and late - the silent damage of non-interactive software

Performance is not just about clicking users and slow screens. Even software without direct interaction has a huge impact on your organization. It's just less noticeable.

Take loading a data warehouse. That happens at night, without anyone waiting for it. Yet here performance makes the difference between “ready at 6:00” or "ready at 10:30. And those few hours of delay? Those mean you don't have your morning reports. Or that you're making decisions based on outdated data.

Or look at order processing. When back-end systems run slow, physical processes are delayed. Orders that go out the door a day late. Every customer who drops out because of this costs money directly (not just lost sales but having to replace them). Teams at a standstill because the system is "still working.

Not to mention the cost. Because inefficient software requires more of your infrastructure. More CPU, more memory, more disk space, bigger licenses ... Result: a higher cloud bill. Every unnecessary loop, faulty query or suboptimal structure is paid dearly.

Slow systems may seem “good enough” on paper. In reality, they cause a silent chain reaction:

• Too slow availability of information
• Process turnaround times that are too slow
• Operational costs that are too high

Many times without anyone applying the brakes.

That's why you need to measure performance not only in milliseconds, but also in customer impact, delays and costs. Even - and especially - with software running in the background.

Because there too: time is money and slow is not acceptable.

Measuring is knowing - but understanding is striking gold

How do you know if your software is fast enough? It starts - as always - with measurement. Because without measurement data, you're in the dark. You see that the system “feels slow,” but you can't substantiate it, make it tangible. Let alone solve it.

But measurement alone is not enough.

Many tools can show that something is slow. A spike in response time, a delayed database query, a full CPU. But then? Then you have data. But no insight yet. Because the why of the observed data often remains unclear. And without that why, no solution is possible.

To really understand performance, you need specialized knowledge. Of how software works internally. How components work together. How data flows. Where bottlenecks occur. And which optimizations do deliver something and which mainly cost money without results.

As an organization, you don't need that kind of knowledge on a daily basis. At the same time, you cannot do without performance expertise.

Therefore, a fully managed optimization service is often much more effective than buying a tool yourself. You then not only get measurements, but also interpretation. No dashboard to analyze yourself, but concrete advice from experts. And - more importantly - improvement actions that work and produce immediate results.

No more treating symptoms, but performance that is put in order structurally, without overcharging your own people or letting expensive tooling gather dust.

In short: measuring is knowing. But if you really want to improve, you need someone who understands what you are measuring - and what you have to do with those measurements.

Fixing is the beginning - preserving is the real gain

Once you know why your software is slow, you can fix it. Rewrite an overloaded query. Split an overloaded application layer. Address a caching problem. Often these are not mega jobs, but smart interventions that make an immediate and noticeable difference.

But it may not end there.

Did you know that software wears out? Not literally of course but still ... it wears out because of everything around it:

• New database versions that handle queries differently.

• Operating systems that prioritize features or optimizations differently.

• Hardware changes that give just different latency.

• More users, more data, more integrations - all impacting performance.

What ran smoothly yesterday may begin to falter tomorrow. Especially if scale increases or changing workloads are not spotted in time.

That's why optimization is not a one-time action. It is a process. Better said, a continuous process.

My advice: put your software under the proverbial magnifying glass every quarter or six months. Please don't wait until users complain or customers drop out. By identifying bottlenecks early on, you keep systems healthy, prevent escalation and save money.

With a good monitoring and analysis tool you can partly automate this. But the real value is in the interpretation. Getting that ‘why’ above water and doing something with it.

This way you avoid hopping from fix to fix and you build a stable foundation. One that remains scalable. Remains agile. And performs future-proof.

Because good performance is not a project. It's a habit and part of a healthy organization.

Want to know how much speed you are leaving behind.

Your processes are running. Your customers are being served. Your people are working hard. But ... is your software working against you without you noticing?

In many organizations, slow performance is a silent killer. No crash. No red alert. Just: wait times that add up. Processes slowing down. Customers who are slightly less satisfied. Employees who click unnecessarily. And an IT bill that just keeps growing.
