We want your thoughts about experimental WebXPRT 4 workloads

Two weeks ago, we discussed how users can automate WebXPRT 4 testing by appending several parameters and values to the benchmark’s URL. One of these lets you enable any available experimental workloads during the test run. While we don’t currently offer any experimental workloads for WebXPRT 4, we are seeking suggestions for possible future workload scenarios, or specific web technologies that you’d like to be able to test with an experimental workload.

The main purpose of optional, experimental workloads would be to test cutting-edge browser technologies or new use cases, even if the experimental workload doesn’t work on all browsers or devices. The individual scores for the experimental workloads would stand alone, and would not factor in the WebXPRT 4 overall score. WebXPRT 4 testers would be able to run the experimental workloads one of two ways: by adjusting a value in the WebXPRT 4 automation scripts, as mentioned above, or by manually selecting them on the benchmark’s home screen.

Testers would benefit from experimental workloads by learning how well certain browsers or systems handle new tasks (e.g., new web apps or AI capabilities). We would benefit from fielding workloads for large-scale testing and user feedback before we commit to including them as core WebXPRT workloads.

Do you have any general thoughts about experimental workloads for browser performance testing, or any specific workloads that you’d like us to consider? Please let us know.

Looking forward to an important WebXPRT milestone

February 28, 2013 was a momentous day for the BenchmarkXPRT Development Community. On that day, we published a press release announcing the official launch of the first version of the WebXPRT benchmark, WebXPRT 2013. As difficult as it is for us to believe, the 10-year anniversary of the initial WebXPRT launch is in just a few short months!

We introduced WebXPRT as a truly unique browser performance benchmark in a field that was already crowded with a variety of measurement tools. Since those early days, the WebXPRT market presence has grown from a small foothold into a worldwide industry standard. Over the years, hundreds of tech press publications have used WebXPRT in thousands of articles and reviews, and the WebXPRT completed-runs counter rolled over the 1,000,000-run mark.

New web technologies are continually changing the way we use the web, and browser-performance benchmarks should evaluate how well new devices handle the web of today, not the web of several years ago. While some organizations have stopped development for other browser performance benchmarks, we’ve had the opportunity to continue updating and refining WebXPRT. We can look back at each of the four major iterations of the benchmark—WebXPRT 2013, WebXPRT 2015, WebXPRT 3, and WebXPRT 4—and see a consistent philosophy and shared technical lineage contributing to a product that has steadily improved.

As we get closer to the 10-year anniversary of WebXPRT next year, we’ll be sharing more insights about its reach and impact on the industry, discussing possible future plans for the benchmark, and announcing some fun anniversary-related opportunities for WebXPRT users. We think 2023 will be the best year yet for WebXPRT!

The XPRTs: What would you like to see?

One of the core principles of the BenchmarkXPRT Development Community is a commitment to valuing the feedback of both community members and the larger group of testers that use the XPRTs on a regular basis. That feedback helps us to ensure that as the XPRTs continue to grow and evolve, the resources that we offer will continue to meet the needs of those that use them.

In the past, user feedback has influenced specific aspects of our benchmarks such as the length of test runs, user interface features, results presentation, and the removal or inclusion of specific workloads. More broadly, we have also received suggestions for entirely new XPRTs and ways we might target emerging technologies or industry use cases.

As we approach the second half of 2022 and begin planning for 2023, we’re asking to hear your ideas about new XPRTs—or new features for existing XPRTs. Are you aware of hardware form factors, software platforms, or prominent applications that are difficult or impossible to evaluate using existing performance benchmarks? Are there new technologies we should be incorporating into existing XPRTs via new workloads? Can you recommend ways to improve any of the XPRTs or XPRT-related tools such as results viewers?

We are interested in your answers to these questions and any other ideas you have, so please feel free to contact us. We look forward to hearing your thoughts!

Here’s what to expect in the WebXPRT 4 Preview

A few months ago, we shared detailed information about the changes we expected to make in WebXPRT 4. We are currently doing internal testing of the WebXPRT 4 Preview build in preparation for releasing it to the public. We want to let our readers know what to expect.

We’ve made some changes since our last update and some of the details we present below could still change before the preview release. However, we are much closer to the final product. Once we release the WebXPRT 4 Preview, testers will be able to publish scores from Preview build testing. We will limit any changes that we make between the Preview and the final release to the UI or features that are not expected to affect test scores.

General changes

Some of the non-workload changes we’ve made in WebXPRT 4 relate to our typical benchmark update process.

  • We have 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 have 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 have not yet added a looping function to the automation scripts, but are still considering it for the future.
  • We investigated the possibility of shortening the benchmark by reducing the default number of iterations from seven to five, but have decided to stick with seven iterations to ensure that score variability remains acceptable across all platforms.

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.

Experimental workloads

As part of the WebXPRT 4 development process, we researched the possibility of including two new workloads: a natural language processing (NLP) workload, and an Angular-based message scrolling workload. After much testing and discussion, we have decided to not include these two workloads in WebXPRT 4. They will be good candidates for us to add as experimental WebXPRT 4 workloads in 2022.

The release timeline

Our goal is to publish the WebXPRT 4 preview build by December 15th, which will allow testers to publish scores in the weeks leading up to the Consumer Electronics Show in Las Vegas in January 2022. We will provide more detailed information about the GA timeline here in the blog as soon as possible.

If you have any questions about the details we’ve shared above, please feel free to ask!

Thinking about experimental WebXPRT workloads in 2022

As the WebXPRT 4 development process has progressed, we’ve started to discuss the possibility of offering experimental WebXPRT 4 workloads in 2022. These would be optional workloads that test cutting-edge browser technologies or new use cases. The individual scores for the experimental workloads would stand alone, and would not factor in the WebXPRT 4 overall score.

WebXPRT testers would be able to run the experimental workloads one of two ways: by manually selecting them on the benchmark’s home screen, or by adjusting a value in the WebXPRT 4 automation scripts.

Testers would benefit from experimental workloads by being able to compare how well certain browsers or systems handle new tasks (e.g., new web apps or AI capabilities). We would benefit from fielding workloads for large-scale testing and user feedback before we commit to including them as core WebXPRT workloads.

Do you have any general thoughts about experimental workloads for browser performance testing, or any specific workloads that you’d like us to consider? Please let us know.

A clearer picture of WebXPRT 4

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!
