There are several reasons why customers select one online retailer over another or one streaming service over another, ranging from the kind of service they receive to pricing, quality, and, as you might have guessed from the headline, speed. I’m talking about the speed with which a website loads and responds to user input. I’ll review some of the fundamentals of speed testing in this article, including metrics you should be aware of and the equipment you’ll need to test and monitor performance.
Why do you need to Use Website Speed Testing Tools?
I’d compile a list of the most prevalent website performance metrics to measure for and problems to watch out for because it’s critical to comprehend precisely how speed testing may assist you in creating a better user experience.
Some resources load far too slowly. These can range from fonts and images to various plains and JS files, which cause your website to load slowly.
URL headers. Servers communicate with one another by transferring data back and forth via a request or response using HTTP headers. You must put these requests and responses to the test to ensure that you receive and transmit the correct message between the two. Additionally, this is useful while trying to troubleshoot potential issues.
TMP and FMP. You must pay attention to two highly crucial metrics: Time to First Byte and First Meaningful Paint. They will display to you when your website loads and the instant information begins to appear.
An explanation of page speed tools
Although each has its subtleties, a page speed tool examines a website and provides suggestions for speeding up the page.
Depending on the program you choose to utilize, some offer a page score, a percentage, etc. All instruments are fundamentally bi-directional in that they strongly suggest the same things, even though the scores may differ significantly.
You can speed up your website’s loading after you know the problems are slowing it down. It entails providing a better end-user experience, which can significantly reduce bounce rate, time spent on a page, and other metrics.
Here are many page speed tools out there that you can start using today. Here are the top tools I recommend.
Types of Performance Testing
There are some significant types of performance testing: –
- Volume Testing: – When the code still being developed, very little data uses for testing. The effectiveness of the software assessed through volume testing, also referred to as “flood testing,” which looks at how it works when faced with large amounts of data. Data loss, system response times, and data storage dependability, among other things, are all examined.
- Load Testing: – Load testing ascertains how the software operates with an increase in workload over a specific period. Concurrent users, transaction volume, software behavior, etc., can all considered workloads. It seeks to track reaction times, throughput rates, resource usage, and other factors. You can improve the end-user experience by finding performance bottlenecks in these properties before launching the application.
- Scalability Testing: – Testing for scalability determines how well the program can manage a growing workload. Scalability testing can done by progressively expanding users or data volume while keeping an eye on the software’s performance. The test will show how it behaves when you scale up or down the software’s performance attributes.
- Stress Testing: – Website performance measure during stress tests outside the usual operating range. More users, transactions, and other forms of increased traffic applied to the software to test how well it operates when used beyond its capacity limits. This testing’s objective is to ascertain the software’s stability. It measures the application’s breaking point based on resource use by taxing hardware resources like CPU, memory, disc space, etc. It aids in your comprehension of the website’s failure and recovery process. For instance, businesses conduct stress testing to evaluate the functionality of their e-commerce apps before significant events like Black Friday.
- Spike Testing: – A form of stress testing known as “spike testing” evaluates website performance under a rapid and considerable increase in demand, similar to that experienced by simulated users. It informs you if the website can handle that sudden and repeated abrupt increase in workload.
- Endurance Evaluation: – Endurance testing, also referred to as soak testing, assesses the website’s performance over an extended period with a consistent, fixed workload. It establishes how long the website can withstand a constant workload to ensure long-term sustainability. During this testing, test teams monitor KPIs like memory leaks, memory utilization, memory shortages, and more. Response times and throughput are also analyzed during endurance testing to see if they remain constant.
The 5 Best Website Speed & Performance Testing Tools
Google Page Speed Insights: –
Long used as the standard tool for assessing and testing websites, Google PageSpeed Insights. It’s a simple Google tool that rates WebPages for desktop and mobile on a scale of 1 to 100. The number increases the faster the website is.
The user interface is simple and only has one input field for the URL. Under each section, a selection of suggested activities that make the page load faster is available for you to select from. Detailed information on concerns, such as render-blocking code, TTFB, page widths, and more, will be sent to you when the test has been completed.
Unlike many tools, Google Page Speed Insights will not allow you to alter queries, set up alerts, or choose other locations to test. On the other hand, there is no need to register, and it is free.
Pingdom Speed Test Tool: –
Pingdom another widely used website speed test tool that has been around for some time. It does not require logging in, although its findings are less comprehensive than those from Google PageSpeed Insights. On a scale from 0 to 100, the site’s performance scored, and details on response codes, content size, request types, requests by domain, and a waterfall chart that details your file load times also offered.
You can use their free tool to run a single test from any of 70 locations, and you can set up page speed monitoring and alerting if you subscribe to their Synthetics service, which starts at $10/month for ten uptime tests.
With GTmetrix, you get access to a wealth of data regarding your page speed, timings, performance score, and much more. Details on how to solve GTmetrix provides the issues the test identified.
You can only administer a test from one location if you don’t register. Vancouver, Canada; however, you’ll be able to choose your location, browser, and connection type once you’ve created a free account. It gives you a clearer idea of how your website works in different scenarios.
Uptrends provides a simple test from one of ten locations, and you can choose the test from a PC or a mobile device. For the desktop test, you may additionally select the screen resolution and one of four browsers (Chrome, Firefox, PhantomJS, and IE) in addition to bandwidth limiting to evaluate the site under various speed conditions.
With the free version of the test, there is typically some quietness, and there no alerts that can be set up, but if you subscribe to their Uptrends Synthetics product, you’ll get all of those things and more for ten basic monitors, RUM, and 60 message credits.
DareBoost conducts a thorough analysis of desktop and mobile devices from various locations worldwide. Although their dashboard straightforward, it contains a wealth of information, including the First Byte, the time it begins rendering the page, the minute it is finished, and advice on enhancing overall efficiency.
It provides premium services with one monitor For website, they also offer more significant subscriptions, including ten users, 15 monitor pages, and monitoring intervals of 30 minutes.
Conclusion – There are many options available, each with a unique characteristic. As you can guess, it’s up to you to test them all and decide which works best for you. Read our post on testing website speed if you’re getting started accurately. It would be best if you undertook speed testing long after creating the website.
