As 2022 gets underway, we want to take this opportunity to look back on 2021 and review another productive year for the XPRTs. Readers of our newsletter are familiar with the stats and updates we include each month, but for our blog readers who don’t receive the newsletter, we’ve compiled some highlights below.

Benchmarks
In the past year, we released the WebXPRT 4 Preview, CloudXPRT v1.1, and an updated CrXPRT 2 build that included a fix for prior issues with the battery life test.

XPRTs in the media
Journalists, advertisers, and analysts referenced the XPRTs thousands of times in 2021. It’s always rewarding to know that the XPRTs have proven to be useful and reliable assessment tools for technology publications such as AnandTech, Expert Reviews, Gadgets 360, Gizmodo, Hot Hardware, Laptop Mag, Legit Reviews, Notebookcheck, PCMag, PCWorld, TechPowerUp, Tom’s Hardware, and ZDNet.

Downloads and confirmed runs
In 2021, we had more than 23,600 benchmark downloads and 228,900 confirmed runs. Our most popular benchmark, WebXPRT, just passed 909,800 runs since its debut in 2013! WebXPRT continues to be a go-to, industry-standard performance benchmark for OEM labs, vendors, and leading tech press outlets around the globe.

Media, publications, and interactive tools
Part of our mission with the XPRTs is to produce tools and materials that help testers better understand the ins and outs of benchmarking in general and the XPRTs in particular. To help achieve this goal, we published the following in 2021:

We’re thankful for everyone who has used the XPRTs, joined the community, and sent questions and suggestions throughout 2021. We look forward to an exciting 2022!

A clearer picture of WebXPRT 4

Justin Greene
By Justin Greene
on October 7, 2021

The WebXPRT 4 development process is far enough along that we’d like to share more about changes we are likely to make and a rough target date for publishing a preview build. While some of the details below will probably change, this post should give readers a good sense of what to expect.

General changes

Some of the non-workload changes in WebXPRT 4 relate to our typical benchmark update process, and a few result directly from feedback we received from the WebXPRT tech press survey.

  • We will update the aesthetics of the WebXPRT UI to make WebXPRT 4 visually distinct from older versions. We do not anticipate significantly changing the flow of the UI.
  • We will update content in some of the workloads to reflect changes in everyday technology. For instance, we will upgrade most of the photos in the photo processing workloads to higher resolutions.
  • In response to a request from tech press survey respondents, we are considering adding a looping function to the automation scripts.
  • We are investigating the possibility of shortening the benchmark by reducing the default number of iterations from seven to five. We will only make this change if we can ensure that five iterations produce consistently low score variance.

Changes to existing workloads

  • Photo Enhancement. This workload applies three effects to two photos each (six photos total). It tests HTML5 Canvas, Canvas 2D, and JavaScript performance. The only change we are considering is adding higher-resolution photos.
  • Organize Album Using AI. This workload currently uses the ConvNetJS neural network library to complete two tasks: (1) organizing five images and (2) classifying the five images in an album. We are planning to replace ConvNetJS with WebAssembly (WASM) for both tasks and are considering upgrading the images to higher resolutions.
  • Stock Option Pricing. This workload calculates and displays graphic views of a stock portfolio using Canvas, SVG, and dygraph.js. The only change we are considering is combining it with the Sales Graphs workload (below).
  • Sales Graphs. This workload provides a web-based application displaying multiple views of sales data. Sales Graphs exercises HTML5 Canvas and SVG performance. The only change we are considering is combining it with the Stock Option Pricing workload (above).
  • Encrypt Notes and OCR Scan. This workload uses ASM.js to sync notes, extract text from a scanned receipt using optical character recognition (OCR), and add the scanned text to a spending report. We are planning to replace ASM.js with WASM for the Notes task and with WASM-based Tesseract for the OCR task.
  • Online Homework. This workload uses regex, arrays, strings, and Web Workers to review DNA and spell-check an essay. We are not planning to change this workload.

Possible new workloads

  • Natural Language Processing (NLP). We are considering the addition of an NLP workload using ONNX Runtime and/or TensorFlowJS. The workload would use Bidirectional Encoder Representations from Transformers (BERT) to answer questions about a given text. Similar use cases are becoming more prevalent in conversational bot systems, domain-specific document search tools, and various other educational applications.
  • Message Scrolling. We are considering developing a new workload that would use an Angular or React.js to scroll through hundreds of messages. We’ll share more about this possible workload as we firm up the details.

The release timeline

We hope to publish a WebXPRT 4 preview build in the second half of November, with a general release before the end of the year. If it looks as though that timeline will change significantly, we’ll provide an update here in the blog as soon as possible.

We’re very grateful for all the input we received during the WebXPRT 4 planning process. If you have any questions about the details we’ve shared above, please feel free to ask!

Investigating the possibility of WebXPRT user accounts

Justin Greene
By Justin Greene
on September 2, 2021

One of our goals during the ongoing WebXPRT 4 development process is to be as responsive as possible to user feedback, and we want to emphasize that it’s not too late to send us your ideas. Until we finalize the details for each workload and complete the code work for the preview build, we still have quite a bit of flexibility around adding new features.

Just this week, a community member raised the possibility of a WebXPRT 4 feature that would enable user-specific test ID numbers or accounts. One possible implementation of the idea would allow a user to sign up for a WebXPRT test account as an individual or on behalf of their organization. The test accounts would be both free and optional; you could continue to run the benchmark without an account, but running it with an account would let you save and view your test history. Another implementation option we are considering would let users generate a permanent user ID number for themselves or their organization. They could then use that number to tag and search for their automated test runs in our database, without having to log into an account.

Our biggest question at the moment is whether our user base would be interested in WebXPRT user accounts or test IDs. If this concept piques your interest, or you have suggestions for implementation, please let us know!

Round 2 of the WebXPRT 4 survey is now open

Justin Greene
By Justin Greene
on July 22, 2021

In May, we surveyed longtime WebXPRT users regarding the types of changes they would like to see in a WebXPRT 4. We sent the survey to journalists at several tech press outlets, and invited our blog readers to participate as well. We received some very helpful feedback. As we explore new possibilities for WebXPRT 4, we’ve decided to open an updated version of the survey. We’ve adjusted the questions a bit based on previous feedback and added some new ones, so we invite you to respond even if you participated in the original survey.

To do so, please send your answers to the following questions to benchmarkxprtsupport@principledtechnologies.com before July 31.

  • Do you think WebXPRT 3’s selection of workload scenarios is representative of modern web tasks?
  • How do you think WebXPRT compares to other common browser-based benchmarks, such as JetStream, Speedometer, and Octane?
  • Would you like to see a workload based on WebAssembly (WASM) in WebXPRT 4? Why or why not?
  • Would you like to see a workload based on Single Page Application (SPA) technology in WebXPRT 4? Why or why not?
  • Would you like to see a workload based on Motion UI in WebXPRT 4? Why or why not?
  • Would you like to see us include any other web technologies in additional workloads?
  • Are you happy with the WebXPRT 3 user interface? If not, what UI changes would you like to see?
  • Have you ever experienced significant connection issues when testing with WebXPRT?
  • Given its array of workloads, do you think the WebXPRT runtime is reasonable? Would you mind if the average runtime increased slightly?
  • Would you like to see us change any other aspects of WebXPRT 3?


If you would like to share your thoughts on any topics that the questions above do not cover, please include those in your response. We look forward to hearing from you!

Feedback from the WebXPRT 4 tech press survey

Justin Greene
By Justin Greene
on June 10, 2021

In early May, we sent a survey to members of the tech press who regularly use WebXPRT in articles and reviews. We asked for their thoughts on several aspects of WebXPRT, as well as what they’d like to see in the upcoming fourth version of the benchmark. We also published the survey questions here in the blog, and invited experienced WebXPRT testers to send their feedback as well. We received some good responses to the survey, and for the benefit of our readers, we’ve summarized some of the key comments and suggestions below.

  • One respondent stated that WebXPRT is demanding enough to test performance, but if we want to simulate modern web usage, we should find the most up-to-date studies on common browser tasks and web technologies. This suggestion lines up with our intention to study the feasibility of adding a WebAssembly workload. 
  • One respondent liked that fact that unlike many other browser benchmarks, WebXPRT tests more than just JavaScript calculation speed.
  • One respondent suggested that we include a link to a WebXPRT white paper within the UI, or at least a guide describing what happens during each workload.
  • One respondent stated that they would like for WebXPRT to automatically produce a good result file on the local test system.
  • One respondent said that WebXPRT has a relatively long runtime for a browser benchmark, and they would prefer that the runtime not increase in WebXPRT 4.
  • We had no direct calls for a battery life test, because many testers already have scripts and/or methodologies in place for battery testing, but one tester suggested adding the ability to loop the test so users can measure performance over varying lengths of time.
  • There were no requests to bring back any aspects of WebXPRT 2015 that we removed in WebXPRT 3.
  • There were no reports of significant connection issues when testing with WebXPRT.

We greatly appreciate the members of the tech press that responded to the survey. We’re still in the planning stages of WebXPRT 4, so there’s still time for anyone to send comments or ideas to benchmarkxprtsupport@principledtechnologies.com. We look forward to hearing from you!

The WebXPRT 4 tech press feedback survey

Justin Greene
By Justin Greene
on May 6, 2021

Device reviews in publications such as AnandTech, Notebookcheck, and PCMag, among many others, often feature WebXPRT test results, and we appreciate the many members of the tech press that use WebXPRT. As we move forward with the WebXPRT 4 development process, we’re especially interested in learning what longtime users would like to see in a new version of the benchmark.  

In previous posts, we’ve asked people to weigh in on the potential addition of a WebAssembly workload or a battery life test. We’d also like to ask experienced testers some other test-related questions. To that end, this week we’ll be sending a WebXPRT 4 survey directly to members of the tech press who frequently publish WebXPRT test results.

Regardless of whether you are a member of the tech press, we invite you to participate by sending your answers to any or all the questions below to benchmarkxprtsupport@principledtechnologies.com. We ask you to do so by the end of May.

  • Do you think WebXPRT 3’s selection of workload scenarios is representative of modern web tasks?
  • How do you think WebXPRT compares to other common browser-based benchmarks, such as JetStream, Speedometer, and Octane?
  • Are there web technologies that you’d like us to include in additional workloads?
  • Are you happy with the WebXPRT 3 user interface? If not, what UI changes would you like to see?
  • Are there any aspects of WebXPRT 2015 that we changed in WebXPRT 3 that you’d like to see us change back?
  • Have you ever experienced significant connection issues when testing with WebXPRT?
  • Given the array of workloads, do you think the WebXPRT runtime is reasonable? Would you mind if the average runtime were a bit longer?
  • Are there any other aspects of WebXPRT 3 that you’d like to see us change?

If you’d like to discuss any topics that we did not cover in the questions above, please feel free to include additional comments in your response. We look forward to hearing your thoughts!
