Performance Tests: See How Your Pages Slow Down Before Your Customers Do

A page that takes six seconds to load doesn't trigger any technical alerts. It just drives the user away. Mr Suricate the actual time of your user journeys, step by step, as often as you choose.

A slow app is still an app that works

That’s what makes this issue so challenging. Nothing is wrong—the monitoring system shows everything is fine—and yet the command tunnel is taking three times as long as it did a month ago. The degradation is gradual; no one inside the system notices it, and it first becomes apparent in the abandonment rate. An automated performance test reveals it as it takes hold.

The time it takes to complete the course, not the server's time

What matters is the time between the click and when the screen is actually usable. It is measured throughout the entire user journey, step by step.

You set the acceptable time for each step. If that time is exceeded, an alert is triggered—not another report.

The Shift Over Time

Each run is comparable to the previous one. A 20% decline spread over three weeks is visible in the curve.

The same scenarios run during pre-production and production, at the times when your business is actually busy.

How continuous measurement changes things, line by line

Without continuous measurement
With Mr Suricate
The slow response time is due to customer service.
It goes back to when the threshold was exceeded.
We measure it once the problem has already arisen.
The meter runs continuously, even during charging.
A performance audit provides a snapshot at a given moment.
You'll see the trend, week by week.
The debate centers on feelings.
It covers time frames, step by step.
We're optimizing the homepage, which isn't the problem.
The slowest stage of the route has been identified.
Performance is a one-time project.
This is a line from your weekly report.
ResultThe response time for each critical step, measured continuously and comparable from one week to the next.
Mr Suricate a no-brainer, because he gives you the assurance that there are no problems. Finding just one bug is enough to make the solution pay for itself for an entire year!”

YOUR QUESTIONS

Frequently Asked Questions

The questions teams ask us most often about performance measurement.

What is the difference between a performance test and a load test?

The performance test measures the response time of a workflow under normal, continuous usage conditions. The load test, on the other hand, identifies the breaking point by simulating a massive influx of simultaneous users. The two are complementary and are handled separately.

What exactly is Mr Suricate measuring Mr Suricate

The actual duration of each step in a user journey: load time, response time for an action, and the time it takes for a screen to become usable. The measurement focuses on the business workflow, not on an isolated server metric.

Can we measure production performance?

Yes, and that's actually the most useful scenario. The same scenarios run during pre-production and production, during peak hours for your business. When working with production data, the rule is to use only data created for testing purposes.

How are we notified when a threshold is exceeded?

The alert is sent via the channel you've defined for the relevant scenario: email, Slack, SMS, or a webhook to your own tool. Critical scenarios may have a different channel and time limit than others.

Are mobile apps covered?

Yes. Native iOS and Android apps are run on actual device farms, which allows us to measure response times on the models and OS versions that your customers actually use.

Do you only believe what you see?

A 30-minute demo of your own app. You'll see one of your workflows automated in real time, without writing any code.
