Accessing XPRT source code

Justin Greene

on March 31, 2022

We recently received a question from member of the tech press about whether we would be willing to supply them with the WebXPRT 4 source code, along with instructions for how to set up a local instance of the benchmark for their internal testbed. We were happy to help, and they are now able to automate WebXPRT 4 runs within their own isolated network.

If you’re a new XPRT tester, you may not be aware that we provide free access to the source code for each of the XPRT benchmarks. Publishing XPRT source code is part of our commitment to making the XPRT development process as transparent as possible. By allowing all interested parties to access and review our source code, we’re encouraging openness and honesty in the benchmarking industry and are inviting the kind of constructive feedback that helps to ensure that the XPRTs continue to contribute to a level playing field.

While XPRT source code is available to the public, our approach to derivative works differs from some open-source models. Traditional open-source models 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.”

Accessing XPRT source code is a straightforward process. The source code for CloudXPRT is freely available in our CloudXPRT GitHub repository. If you’d like to download and review the source code for WebXPRT 4 or any of the other XPRTs, or get instructions for how to build one of the benchmarks, all you need to do is contact us at benchmarkxprtsupport@principledtechnologies.com. Your feedback is valuable!

Chrome OS support for CrXPRT apps ends in June 2022

Justin Greene
By Justin Greene
on March 24, 2022

Last March, we discussed the Chrome OS team’s original announcement that they would be phasing out support for Chrome Apps altogether in June 2021, and would shift their focus to Chrome extensions and Progressive Web Apps. The Chrome OS team eventually extended support for existing Chrome Apps through June 2022, but as of this week, we see no indication that they will further extend support for Chrome Apps published with general developer accounts. If the end-of-life schedule for Chrome Apps does not change in the next few months, both CrXPRT 2 and CrXPRT 2015 will stop working on new versions of Chrome OS at some point in June.

To maintain CrXPRT functionality past June, we would need to rebuild the app completely—either as a Progressive Web App or in some other form. For this reason, we want to reassess our approach to Chrome OS testing, and investigate which features and technologies to include in a new Chrome OS benchmark. Our current goal is to gather feedback and conduct exploratory research over the next few months, and begin developing an all-new Chrome OS benchmark for publication by the end of the year.

While we will discuss ideas for this new Chrome OS benchmark in future blog posts, we welcome ideas from CrXPRT users now. What features or workloads would you like the new benchmark to retain? Would you like us to remove any components from the existing benchmark? Does the battery life test in its current form suit your needs? If you have any thoughts about these questions or any other aspects of Chrome OS benchmarking, please let us know!

Exploring the WebXPRT 4 results viewer

Justin Greene
By Justin Greene
on March 17, 2022

Now that WebXPRT 4 is live, we want to remind readers about the features of the WebXPRT 4 results viewer. We’re excited about this new tool, which we view as an ongoing project that we will expand and improve over time. The viewer currently has over 100 test results, and we’re just getting started. We’ll continue to actively populate the viewer with the latest PT-curated WebXPRT 4 results for the foreseeable future.

The screenshot below shows the tool’s default display. Each vertical bar in the graph represents the overall score of a single test result, with bars arranged from lowest to highest. To view a single result in detail, the user hovers over a bar until it turns white and a small popup window displays the basic details of the result. Once the user clicks to select the highlighted bar, the bar turns dark blue, and the dark blue banner at the bottom of the viewer displays additional details about that result.

In the example above, the banner shows the overall score (227), the score’s percentile rank (98th) among the scores in the current display, the name of the test device, and basic hardware disclosure information. Users can click the Run info button to see the run’s individual workload scores.

The viewer includes a drop-down menu to quickly filter results by major device type categories, and a tab that allows users to apply additional filtering options, such as browser type, processor vendor, and result source. The screenshot below shows the viewer after I used the device type drop-down filter to select only laptops.

The screenshot below shows the viewer as I use the filter tab to explore additional filter options, such browser type.

The viewer also lets users pin multiple specific runs, which is helpful for making side-by-side comparisons. The screenshot below shows the viewer after I pinned four runs and viewed them on the Pinned runs screen.

The screenshot below shows the viewer after I clicked the Compare runs button: the overall and individual workload scores of the pinned runs appear as a table.

We’re excited about the WebXPRT 4 results viewer, and we want to hear your feedback. Are there features you’d really like to see, or ways we can improve the viewer? Please let us know, and send us your latest test results!

WebXPRT 4 is live!

Justin Greene
By Justin Greene
on February 28, 2022

We’re excited to announce that WebXPRT 4 is now available! Testers can access the benchmark at WebXPRT.com. If you’ve already been using the WebXPRT 4 Preview, your Preview test results will be comparable with results from the current official build.

Longtime WebXPRT users will notice that WebXPRT 4 has a new, but familiar, UI. The general process for kicking off both manual and automated tests is the same as with WebXPRT 3, so the transition from WebXPRT 3 to WebXPRT 4 testing should be straightforward. We will continue to make WebXPRT 3 available for legacy testing.

If you missed earlier XPRT blog posts about WebXPRT 4, here is a quick overview of the differences between WebXPRT 3 and WebXPRT 4:

General changes

  • We’ve updated the aesthetics of the WebXPRT UI to make WebXPRT 4 visually distinct from older versions. We did not significantly change the flow of the UI.
  • We’ve updated content in some of the workloads to reflect changes in everyday technology, such as upgrading most of the photos in the photo processing workloads to higher resolutions.
  • We’ve updated the base calibration system for score calculations, and adjusted the scoring scale. WebXPRT 4 scores should not be compared to scores from previous versions of WebXPRT.

Workload changes

  • Photo Enhancement. We increased the efficiency of the workload’s Canvas object creation function, and replaced the existing photos with new, higher-resolution photos.
  • Organize Album Using AI. We replaced ConvNetJS with WebAssembly (WASM) based OpenCV.js for both the face detection and image classification tasks. We changed the images for the image classification tasks to images from the ImageNet dataset.
  • Stock Option Pricing. We updated the dygraph.js library.
  • Sales Graphs. We made no changes to this workload.
  • Encrypt Notes and OCR Scan. We replaced ASM.js with WASM for the Notes task and updated the WASM-based Tesseract version for the OCR task.
  • Online Homework. In addition to the existing scenario which uses four Web Workers, we have added a scenario with two Web Workers. The workload now covers a wider range of Web Worker performance, and we calculate the score by using the combined run time of both scenarios. We also updated the typo.js library.

We’re thankful for all of the feedback we received during the WebXPRT 4 development process, and we look forward to seeing your WebXPRT 4 results!

WebXPRT 4 is almost here!

Justin Greene
By Justin Greene
on February 24, 2022

We’re putting the last pieces in place for the WebXPRT 4 GA, and expect to take the final build live by this time next week! When we released the WebXPRT 4 Preview and encouraged testers to submit and publish results, we said we’d try to limit any changes to things that would not affect test scores. We’re happy to report that we’ve achieved that goal, and Preview testing results are comparable with GA build results.

If you missed the blog post about the differences between WebXPRT 3 and WebXPRT 4, we encourage you to check it out. Everything we mentioned about the general and workload-specific changes in the Preview build holds true for the upcoming GA.

Keep an eye on the blog and WebXPRT.com for more information in the coming week. We look forward to seeing your test results!

A note about WebXPRT 4 and Internet Explorer

Justin Greene
By Justin Greene
on February 10, 2022

During some recent internal WebXPRT 4 Preview testing, we discovered that the WebXPRT 4 Preview does not run in Internet Explorer (IE) 11. In fact, before the first workload begins in IE, the WebXPRT 4 built-in WebAssembly (WASM) check fails and produces an error message.

The reason we haven’t tested WebXPRT 4 on IE 11 before now is that Internet Explorer is currently in its end-of-life phase. Microsoft has been removing support for IE 11 in Microsoft 365 and other apps for some time, they did not include the desktop version of IE 11 in Windows 11, and they are removing support for IE 11 in Windows 10 on June 15, 2022. Among Windows users, the most popular browsers are now Microsoft Edge, Google Chrome, and Mozilla Firefox.

We’re proud that WebXPRT has historically had broad, cross-platform compatibility in almost any browser. However, the modern web is rapidly incorporating powerful tools such as WASM that do not work in older legacy browsers. To maintain the benchmark’s relevance in future years, we need to deprioritize some level of legacy compatibility, and this begins with WebXPRT 4 release.

For the WebXPRT testers who wish to continue testing with IE 11, WebXPRT 3 will remain on our site for the foreseeable future. Barring any further changes from Microsoft, the benchmark should continue to run in existing instances of the Internet Explorer desktop app.

The official WebXPRT 4 launch is approaching, and we hope to announce the release date within the next few weeks! Until that time, we will continue to share the latest updates here in the blog. If you have any questions or comments about WebXPRT 4 or compatibility with legacy browsers, please feel free to contact us!
