Best tool for measuring loading time of pages?


In the company where I work we are encountering performance issues when loading pages.

I’d like to make an inventory of loading delays for every page. What tool would you recommend ?

Maybe load testing tools like Webload, Loadrunner etc ?


I’m mostly used to using JMeter (OpenSource, free & easy to use)

What kind of webpage are we talking about? Do you use REST API’s or still SOAP or something else?
Make sure to keep your performance script ‘realistic’ to ensure correct response-time results.

If you want to go nuts use for example JMeter + TICK Stack: InfluxDB 1.X: Open Source Time Series Platform | InfluxData

  • Telegraph
  • InfluxDB
  • Chronograph (or Grafana)
  • Kapacitor

Insane dashboarding & live followup of your results, highly recommended.


I red that Jmeter is hard to set up, it could take time, is it true ?

I’d like to test it directly in the GUI and not just API calls.

I don’t think so, it’s actually very easy to setup. (TICK Stack is a bit harder to setup)
I don’t think you need a lot of technical skills to setup JMeter either.

This guy explains it all very well

This will be quite difficult in any performance testing tool.
You can do call to retrieve all html, css, etc but … reporting will look dirty.

I would advise to start testing your API’s. Because if your UI loads slow you still won’t know if it’s due to the API or UI.

I don’t know how many users you wish to simulate of course but I can imagine if you want to simulate 10.000 users, you won’t want to spin up 10.000 browsers :stuck_out_tongue:

Yes I understand that testing in the UI is less relevant, but the need of the company is more like from a user point of view. Basically they just want to know what pages takes more than 4 seconds to be loaded.

I agree with you that using the API is the proper way but actually they want to measure the UI performance too.

You can always test it manually and look at the response times in Developer Tools.
What sometimes happens is that you use JMeter to set load on the web app with 100-10.000 users and then you go manually through the UI while there is a bigger load.

But yea it will never be a proper result :confused:

Like Kist mentioned, with JMeter you would have the most control of what you can check.

But, if you want to start of with something easy (and more visual, since JMeter can see a bit overwhelming with all of it’s options) just try the Lighhouse from the dev tools to get a general idea:

Here are a few more web-based services which offer similar insight:

PS the MoT Club website seem really performant :smiley:


Have a look at this tool. It would provide some insight on how the page is in diferent areas.


Thank you guys for all these answers. I saw different tools like “Fast or Slow” but actually when you have to test a software’s company with real login/pw I think we need different tools like Jmeter, isn’t it ?

Basically we have to be able to run a real scenario where you navigate into pages or you call API, not just ping a public page like where we are right now :smiley:

In the past I coordinated performance tests with LoadRunner and JMeter.

LoadRunner is an expensive tool, but it has also a lot of features. For a normal load test and stress test this tool can provide a lot of information.

JMeter is a cheap tool for a load test. It has less features than LoadRunner, but it might be suitable for a small test.

The most difficult part of the performance test is to interpret the data. Suppose the load time of a page is 5 seconds. What is the bottleneck?


In my opinion, there is no tool better than Apache Jmeter to use when you need to work on load tests.

Being VP Delivery and Operations, at Software Testing Company here is the blog that may help you better understand JMeter Tool: Introduction to JMeter & How to View JMeter Test Results in Real-time?


Depends what you are looking to do?

To monitor production systems with synthetic checks, pingdom, speedcurve, wepagetest, or gmetrics are not a bad idea.

For performance testing prior to release I’ve been moving teams away to jmeter to k6. See my testbash talk next month as to why.

You might also consider an APM solution (newrlic) or analytics (google analytics, amplitude) for real user metrics .
