Frequently Asked Questions

How is this different than Google PageSpeed Insights or GT Metrix?

PageSpeed Insight and GT Metrix will measure your website current performance but give no data what will happen to your website speed when more users come in for example on Black Friday.

The amount concurrent users is probably the biggest factor affecting your website speed and those tools completely ignore that.With supervisor.com you can test your website with any amount of users and see how fast your website is on Black Friday.

Check out this video demonstrating this.



With how many users I could check?

We wil scale to to hundreds of thousands of users and beyond based on your need but we also support testing with smaller amounts. What ever is your requirement.

Why should I test if I have autoscaling, CDN, a big server...

But do you actually know if those things work or your website and what is limit if you have never tried it?

And how do you know that you have used right configurations for your use case?

Different technologies will help you scale but it's nicer to test that they actually help before the real users do.

Think it as a rehearsal. If it goes wrong you will have time to improve.

What is the testing process?

It is really super simple.

Enter the website address you would like to test.

Give our robots a signal that they can start.

Our robots will open their browsers and log in to your website.

No need to install anything on your servers or website code.

No need to define test scripts.

And it all takes only couple of minutes.

So are you doing DoS attacks?

Each load testing tool could be used for DoS attacks and most of them try include processes that prevent that.

Here's what we do at supervisor.com:

1. You need to verify, that you are connected to the website you are testing with Google Analytics. So the site has to be within those sites, that you have access to in Google Analytics and the site has to have Google Analytics installed.
2. We will always stop the test if the website start to get too slow. Your site should always load under three seconds so there is no reason to go much further. You average website users will not wait 6 seconds for your pages to load.

How does Supervisor load test compare with Blazemeter, Loader.io and Locust

Supervisor.com load test is totally automatic and we monitor the user experience like page load time that is crucial for your business success. We do it by automating software robots that use real web browsers to browse your web site.

These other tools require a lot of work to build test scripts which is time consuming and expensive.

They also only measure things like how many http-requests / second, average requests time and how many percent of requests failed. Those metrics will not translate to User Experience which is important for your websites conversion and bounce rates and don't really tell how many users your website can handle.

It's because all those tools either directly use or follow the methology if Apache JMeter that is open source load tool that was released over 20 years ago.

In order to realistically replicate real user behaviour in your website with those tools, you need script all the different HTTP requests a browsers does to build the website for each and every page on that website.

Each web page could easily have 200 different requests and since browsers will not load them all at the same time you would need to add also some timing to replicate how browser behaviour. And preferably number of different timings because each user is unique.

And of course you would also need to build number of different funnels so that all the users are not clicking trough the same links. And time the transitions from one page to another so that the links are not just clicked with the speed of light.

If you would like to test something more complex like e-commerce websites it would become even harder to replicate things like adding products to shopping cart etc.

All that comes with a click of a button in supervisor.com load test.

How does it work?

We automate software robots that use real browsers to login to your site.

They report their user experience like page load time back to our service so that you will know how fast your website is with any amount of users.
