XPRT mentions in the tech press

One of the ways we monitor the effectiveness of the XPRT family of benchmarks is to regularly track XPRT usage and reach in the global tech press. Many tech journalists invest a lot of time and effort into producing thorough device reviews, and relevant and reliable benchmarks such as the XPRTs often serve as indispensable parts of a reviewer’s toolkit. Trust is hard-earned and easily lost in the benchmarking community, so we’re happy when our benchmarks consistently achieve “go-to” status for a growing number of tech assessment professionals around the world.

Because some of our newer readers may be unaware of the wide variety of outlets that regularly use the XPRTs, we occasionally like to share an overview of recent XPRT-related tech press activity. For today’s blog, we want to give readers a sampling of the press mentions we’ve seen over the past few months.

Recent mentions include:

Each month, we send out a BenchmarkXPRT Development Community newsletter that contains the latest updates from the XPRT world and provides a summary of the previous month’s XPRT-related activity, including new mentions of the XPRTs in the tech press. If you don’t currently receive the monthly BenchmarkXPRT newsletter but would like to join the mailing list, please let us know! There is no cost to join, and we will not publish or sell any of the contact information you provide. We will send only the monthly newsletter and occasional benchmark-related announcements, such as news about patches or new releases.

Working with the WebXPRT 4 source code

In our last blog post, we discussed the WebXPRT 4 source code and how you can contact us to request free access to the build package. In this post, we’ll address two questions that users sometimes ask about code access. The first question is, “How do I build a local instance of WebXPRT?” The second is, “What can I do with it?”

How to build a local WebXPRT 4 instance

After we receive your request, we’ll send you a secure link to the current WebXPRT 4 build package, which contains all the necessary source code files and installation instructions. You will need a system to use as a server, and you will need to be familiar with Apache, PHP, and MySQL configuration to follow the build instructions. WebXPRT 4 uses a LAMP (Linux, Apache, MySQL, and PHP) setup on the “server” side, but it’s also possible to set up an instance with a WAMP or XAMPP stack.

The build instructions include a step-by-step methodology for setup. If you are familiar with LAMP stack configuration, the build and configuration process should take about two to three hours, depending on whether your LAMP-related extensions and libraries are current.

What you can do with a local WebXPRT 4 instance

We allow users to set up their own WebXPRT 4 instances for purposes of review, internal testing, or experimentation.

One use-case example is internal OEM lab testing. Some labs use WebXPRT to conduct extensive testing on preproduction hardware, and they follow stringent security guidelines to avoid the possibility of any hardware or test information leaving the lab. Even though we have our own strict policies about how we handle the little amount of data that WebXPRT gathers from tests, a local WebXPRT 4 instance provides those labs with an extra layer of security for sensitive tests.

We do ask that users publish results only from tests that they run on WebXPRT.com. As we mentioned in our most recent post, benchmarking requires a product that is consistent to enable valid comparisons over time. We allow people to download the source, but we reserve the right to control derivative works and which products can use the name “WebXPRT.” That way, when people see WebXPRT scores in tech press articles or vendor marketing materials, they can run their own tests on WebXPRT.com and be confident that they’re using the same standard for comparison.

Accessing the WebXPRT 4 source code

If you’re new to the XPRTs, you may not be aware that we provide free access to XPRT benchmark source code. Publishing XPRT source code is part of our commitment to making the XPRT development process as transparent as possible. By allowing interested parties to access and review our source code, we’re encouraging openness and honesty in the benchmarking industry. We’re also inviting constructive feedback that can help ensure that the XPRTs continue to improve and contribute to a level playing field for all the types of products they measure.

While we do offer free access to the XPRT source code, we’ve decided to offer the code upon request instead of using a permanent download link. This approach prevents bots or other malicious actors from downloading the code. It also has the benefit of allowing us to interact with users who are interested in the source code and answer any questions they may have. We’re always keen to learn more about what others are thinking about the XPRTs and the types of work they measure.

We recently received some questions about accessing the WebXPRT 4 source code, which made us realize that we needed to make a clearer way for people to ask for the code. In response, we added a “Request WebXPRT 4 source code” link to the gray Helpful Info box on WebXPRT.com (see it in the screenshot below). Clicking the link will allow you to email the BenchmarkXPRT Support team directly and request the code.

After we receive your request, we’ll send you a secure link to the current WebXPRT 4 build package. For those users who wish to set up a local instance of WebXPRT 4 for their own internal testbeds, the package will contain all the necessary files and installation instructions. We allow folks to set up their own instances for purposes of review, internal testing, or experimentation, but we ask that users publish only test results from the official WebXPRT 4 site.

While we offer free access to XPRT source code, our approach to derivative works differs from some traditional open-source models that encourage developers to change products and even take them in different directions. Because benchmarking requires a product that remains static to enable valid comparisons over time, we allow people to download the source, but we reserve the right to control derivative works. This discourages a situation where someone publishes an unauthorized version of the benchmark and calls it an “XPRT.”

WebXPRT in PT reports

We don’t just make WebXPRT—we use it, too. If you normally come straight to BenchmarkXPRT.com or WebXPRT.com, you may not even realize that Principled Technologies (PT) does a lot more than just managing and administering the BenchmarkXPRT Development Community. We’re also the tech world’s leading provider of hands-on testing and related fact-based marketing services. As part of that work, we’re frequent WebXPRT users.

We use the benchmark when we test devices such as Chromebooks, desktops, mobile workstations, and consumer laptops for our clients. (You can see a lot of that work and many of our clients on our public marketing portfolio page.) We run the benchmark for the same reasons that others do—it’s a reliable and easy-to-use tool for measuring how well devices handle web browsing and other web work.

We also sometimes use WebXPRT simply because our clients request it. They request it for the same reason the rest of us like and use it: it’s a great tool. Regardless of job titles and descriptions, most laptop and tablet users surf the web and access web-based applications every day. Because WebXPRT is a browser benchmark, higher scores on it could indicate that a device may provide a superior online experience.

Here are just a few of the recent PT reports that used WebXPRT:

  • In a project for Dell, we compared the performance of a Dell Latitude 7340 Ultralight to that of a 13-inch Apple MacBook Air (2022).
  • In this study for HP, we compared the performance of an HP ZBook Firefly G10, an HP ZBook Power G10, and an HP ZBook Fury G10.
  • Finally, in a set of comparisons for Lenovo, we evaluated the system performance and end-user experience of eight Lenovo ThinkBook, ThinkCentre, and ThinkPad systems along with their Apple counterparts.

All these projects, and many more, show how a variety of companies rely on PT—and on WebXPRT—to help buyers make informed decisions. P.S. If we publish scores from a client-commissioned study in the WebXPRT 4 results viewer, we will list the source as “PT”, because we did the testing.

WebXPRT benchmarking tips from the XPRT lab

Occasionally, we receive inquiries from XPRT users asking for help determining why two systems with the same hardware configuration are producing significantly different WebXPRT scores. This can happen for many reasons, including different software stacks, but score variability can also result from different testing behaviors and environments. While some degree of variability is normal, these types of questions provide us with an opportunity to talk about some of the basic benchmarking practices we follow in the XPRT lab to produce the most consistent and reliable scores.

Below, we list a few basic best practices you might find useful in your testing. Most of them relate to evaluating browser performance with WebXPRT, but several of these practices apply to other benchmarks as well.

  • Hardware is not the only important factor: Most people know that different browsers produce different performance scores on the same system. Testers are not, however, always aware of shifts in performance between different versions of the same browser. While most updates don’t have a large impact on performance, a few updates have increased (or even decreased) browser performance by a significant amount. For this reason, it’s always important to record and disclose the extended browser version number for each test run. The same principle applies to any other relevant software.
  • Keep a thorough record of system information: We record detailed information about a test system’s key hardware and software components, including full model and version numbers. This information is not only important for later disclosure if we choose to publish a result, it can also sometimes help to pinpoint system differences that explain why two seemingly identical devices are producing very different scores. We also want people to be able to reproduce our results to the closest extent possible, so that commitment involves recording and disclosing more detail than you’ll find in some tech articles and product reviews.
  • Test with clean images: We typically use an out-of-box (OOB) method for testing new devices in the XPRT lab. OOB testing means that other than running the initial OS and browser version updates that users are likely to run after first turning on the device, we change as little as possible before testing. We want to assess the performance that buyers are likely to see when they first purchase the device and before they install additional software. This is the best way to provide an accurate assessment of the performance retail buyers will experience from their new devices. That said, the OOB method is not appropriate for certain types of testing, such as when you want to compare as close to identical system images as possible, or when you want to remove as much pre-loaded software as possible.
  • Turn off automatic updates: We do our best to eliminate or minimize app and system updates after initial setup. Some vendors are making it more difficult to turn off updates completely, but you should always double-check update settings before testing.
  • Get a baseline for system processes: Depending on the system and the OS, a significant amount of system-level activity can be going on in the background after you turn it on. As much as possible, we like to wait for a stable baseline (idle time) of system activity before kicking off a test. If we start testing immediately after booting the system, we often see higher variance in the first run before the scores start to tighten up.
  • Use more than one data point: Because of natural variance, our standard practice in the XPRT lab is to publish a score that represents the median from three to five runs, if not more. If you run a benchmark only once and the score differs significantly from other published scores, your result could be an outlier that you would not see again under stable testing conditions or over the course of multiple runs.


We hope these tips will help make your testing more accurate. If you have any questions about WebXPRT, the other XPRTs, or benchmarking in general, feel free to ask!

Comparing the WebXPRT 4 performance of five popular browsers

Every so often, we like to refresh a series of in-house WebXPRT comparison tests to see if recent updates have changed the performance rankings of popular web browsers. We published our most recent comparison last February, when we used WebXPRT 4 to compare the performance of five browsers on the same system.

For this round of tests, we used the same Dell XPS 13 7930 laptop as last time, which features an Intel Core i3-10110U processor and 4 GB of RAM, running Windows 11 Home updated to version 23H2 (22631.307). We installed all current Windows updates, and updated each of the browsers under test: Brave, Google Chrome, Microsoft Edge, Mozilla Firefox, and Opera.

After the update process completed, we turned off updates to prevent them from interfering with test runs. We ran WebXPRT 4 three times on each of the five browsers. The score we post for each browser is the median of the three test runs.

In our last round of tests, the range between high and low scores was tight, with an overall difference of only 4.3 percent. Edge squeaked out a win, with a 2.1 percent performance advantage over Chrome. Firefox came in last, but was only one overall score point behind the tied score of Brave and Opera.

In this round of testing, the rank order did not change, but we saw more differentiation in the range of scores. While the performance of each browser improved, the range between high and low scores widened to a 19.1 percent difference between first-place Edge and last-place Firefox. The scores of the four Chromium-based browsers (Brave, Opera, Chrome, and Edge) all improved by at least 21 points, while the Firefox score only improved by one point. 

Do these results mean that Microsoft Edge will always provide a faster web experience, or Firefox will always be slower than the others? Not necessarily. It’s true that a device with a higher WebXPRT score will probably feel faster during daily web activities than one with a much lower score, but your experience depends in part on the types of things you do on the web, along with your system’s privacy settings, memory load, ecosystem integration, extension activity, and web app capabilities.

In addition, browser speed can noticeably increase or decrease after an update, and OS-specific optimizations can affect performance, such as with Edge on Windows 11 and Chrome on Chrome OS. All these variables are important to keep in mind when considering how WebXPRT results may translate to your everyday experience.

Have you used WebXPRT 4 to compare browser performance on the same system? Let us know how it turned out!
