WebXPRT 3, Mobile World Congress, and the next HDXPRT

on February 8, 2018

We’re excited about everything that’s in store for the XPRTs, and we want to update community members on what to expect in the next few months.

The next major development is likely to be the WebXPRT 3 general release. We’re currently refining the UI and conducting extensive testing with the community preview build. We’re not ready to announce a firm release date, but hope to do so over the next few weeks. Please try the community preview and give us your feedback, if you haven’t already.

During the last week of February, Mark will be at Mobile World Congress (MWC) in Barcelona. Each year, MWC offers a great opportunity to examine the new trends and technologies that will shape mobile technology in the years to come. We look forward to sharing Mark’s thoughts on this year’s hot topics. Will you be attending MWC this year? If so, let us know!

In addition, we’re hoping to have a community preview of the next HDXPRT ready in the spring. As we mentioned a few months ago, we’re updating the workloads, applications, and UI. For the converting photos scenario, we’re considering incorporating new Adobe Photoshop tools such as the “Open Closed Eyes” feature and an automatic fix for pictures that are out of focus due to handheld camera shake. For the converting videos scenario, we’re including 4K GoPro footage that represents the quality of video captured by today’s “prosumer” demographic.

What features would you like to see in the next HDXPRT? Let us know!

The WebXPRT 3 Community Preview is here!

By Justin Greene

on December 14, 2017

Today we’re releasing the WebXPRT 3 Community Preview (CP). As we discussed in the blog last month, in the new version of WebXPRT, we updated the photo-related workloads with new images and a new deep learning task for the Organize Album workload. We also added an optical character recognition task to the Local Notes workload and combined a portion of the DNA Sequence Analysis scenario with a writing sample/spell check scenario to simulate an online homework hub in the new “Online Homework” workload.

Also, longtime WebXPRT users will immediately notice a completely new, but clean and straightforward, UI. We’re still tweaking aspects of the UI and implementing full functionality for certain features such as social media sharing and German language translation, but we don’t anticipate making any significant changes to the overall test or individual workloads before the general release.

As with all community previews, the WebXPRT 3 CP is available only to BenchmarkXPRT Development Community members, who can access the link from the WebXPRT tab in the Members’ Area.

After you try the WebXPRT 3 CP, please send us your comments. Thanks and happy testing!

News about WebXPRT and BatteryXPRT

By Justin Greene

on December 7, 2017

Last month, we gave readers a glimpse of the updates in store for the next WebXPRT, and now we have more news to report on that front.

The new version of WebXPRT will be called WebXPRT 3. WebXPRT 3 will retain the convenient features that made WebXPRT 2013 and WebXPRT 2015 our most popular tools, with more than 200,000 combined runs to date. We’ve added new elements, including AI, to a few of the workloads, but the test will still run in 15 minutes or less in most browsers and produce the same easy-to-understand results that help compare browsing performance across a wide variety of devices.

We’re also very close to publishing the WebXPRT 3 Community Preview. For those unfamiliar with our open development community model, BenchmarkXPRT Development Community members have the ability to preview and test new benchmark tools before we release them to the general public. Community previews are a great way for members to evaluate new XPRTs and send us feedback. If you’re interested in joining, you can register here.

In BatteryXPRT news, we recently started to see unusual battery life estimates and high variance when running battery life tests at the default length of 5.25 hours. We think this may be due to changes in how new OS versions are reporting battery life on certain devices, but we’re in the process of extensive testing to learn more. In the meantime, we recommend that BatteryXPRT users adjust the test run time to allow for a full rundown.

Do you have questions or comments about WebXPRT or BatteryXPRT? Let us know!

How to submit results for the WebXPRT Processor Comparison Chart

By Justin Greene

on November 30, 2017

The WebXPRT 2015 Processor Comparison Chart is in its second month, and we’re excited to see that people are browsing the scores. We’re also starting to receive more WebXPRT score submissions for publication, so we thought it would be a good time to describe how that process works.

Unlike sites that publish any results they receive, we hand-select results from internal lab testing, end-of-test user submissions, and reliable tech media sources. In each case, we evaluate whether the score is consistent with general expectations. For sources outside of our lab, that evaluation includes checking to see whether there is enough detailed system information to get a sense of whether the score makes sense. We do this for every score on the WebXPRT results page and the general XPRT results page.

If we decide to publish a WebXPRT result, that score automatically appears in the processor comparison chart as well. If you would like to submit your score, the submission process is quick and easy. At the end of the WebXPRT test run, click the Submit button below the individual workload scores, complete the short submission form, and click Submit again. The screenshot below shows how the form would look if I submitted a score at the end of a WebXPRT run on my personal system.

After you submit your score, we’ll contact you to confirm the name we should display as the source for the data. You can use one of the following:

Your first and last name
“Independent tester,” if you wish to remain anonymous
Your company’s name, provided that you have permission to submit the result in their name. If you want to use a company name, we ask that you provide your work email address.

We will not publish any additional information about you or your company without your permission.

We look forward to seeing your score submissions, and if you have suggestions for the processor chart or any other aspect of the XPRTs, let us know!

Glimpses of the next WebXPRT

By Justin Greene

on November 2, 2017

Development work on the next version of WebXPRT is well underway, and we think it’s a good time to offer a glimpse of what’s to come.

We’ve updated the photo-related workloads with new images and are experimenting with adding a new task to the Organize Album workload. The task utilizes ConvNetJS, a JavaScript library designed for training neural networks within the browser itself, to assign classifications to a set of images. It’s an example of the type of integrated deep learning tasks that will be showing up in all sorts of devices in the years to come.

We’re also testing an additional task in the Local Notes workload using Tesseract.js, a popular OCR (optical character recognition) engine. Our scenario uses OCR technology to scan images of purchase receipts and gather relevant information.

We’re testing these new tasks now, and will include them only once we’re confident that they produce consistent and reliable results without extending the benchmark’s runtime unnecessarily. Consequently, the next WebXPRT might contain variations of these tasks, or other new technologies altogether. We mention them now to offer some insight into the types of workload enhancements that we’re considering.

We’ve been working hard on the new WebXPRT UI as well. The image below shows the new start page from an early development build. We’re still making adjustments, so the final product will probably differ, but you do get a sense of the new UI’s clean look.

As we’ve said before, we’re committed to making sure that WebXPRT runs in most browsers and produces results that are useful for comparing web browsing performance across a wide variety of devices. We appreciate the feedback we’ve gotten so far, and are happy to receive more. Do you have ideas for the next WebXPRT? Let us know!

Looking for performance clues

By Eric Hale

on October 26, 2017

We’ve written before about how the operating system and other software can influence test scores and even battery life. Benchmarks like the XPRTs provide overall results, but teasing out which factors affect those results may require some detective work. The key is to collect individual data points as evidence to what may be causing performance changes.

The Apple iOS 11 rollout last month is an excellent example of the effect of software on device performance. Angry tweets started almost immediately after the update, claiming that iOS 11 drained device batteries. iPhone users here at PT experienced similar issues. What was the cause of that performance drop? The hardware remained the same. So, did software cause the problem?

Less than a week after the rollout, Mashable published an explanation of possible causes. The article quotes research from mobile security firm Wandera showing that, for the 50,000 “moderate to heavy iPhone and iPad users” in the study, devices running iOS 11 burned through their battery at much faster rates than the same devices running iOS 10. They cite two possible causes:

devices often re-categorize the files stored on them for every new OS install, which may account for some of the battery issues.
many apps are not optimized for iOS 11 yet.

While these explanations make sense, with a little more digging, we could get closer to actually solving the mystery instead of guessing at the causes. After all, it is also possible that people are using iOS 11 differently from iOS 10. So, how could a dedicated sleuth investigate further? Anyone using benchmarks and hands-on testing to sift through various scenarios and configurations could get us closer to solving this mystery and any other software-based performance anomalies. But it’s a daunting task—changing only one variable at a time and recording the results is like pounding the streets and knocking on doors to solve a case.

In all likelihood, some combination of Apple iOS updates and application changes will improve the battery life for iOS 11. In the meantime, we wish we had an XPRT that could test battery life on iOS. Who knows, maybe some future version of WebXPRT will be able to help in future sleuthing.
