WebKit launches JetStream2 browser benchmark

WebKit launched JetStream 2, a new benchmark suite to measure the performance of JavaScript and WebAssembly operations in web browsers recently.
Browser benchmarks were a huge thing back when Google Chrome launched. Google used them to demonstrate how much faster Chrome's JavaScript performance was when compared to Internet Explorer or Firefox, the two main browsers back in the day.
One of the effects was that browser makers started to optimize and improve the performance of JavaScript; this resulted in benchmarks becoming less important as speed improved in browsers.
JetStream 2
JetStream 2 tests JavaScript and WebAssembly performance of web browsers as well as the performance of other functions such as Web Workers. Just hit the start button on the JetStream 2 benchmark website to test the browser.
JetStream 2 also includes a new set of benchmarks that measure the performance of Web Assembly, Web Workers, Promises, async iteration, unicode regular expressions, and JavaScript parsing.
The browser benchmark runs 64 tests, some of which come from other benchmarks such as JetStream, SunSpider, or Octane. The development team describes each of the tests that JetStream 2 runs on this page.
The team ran the benchmark on a MacBook Pro to compare the results of Safari, Chrome and Firefox. Safari took the crown in the test followed by Chrome (about 8% slower) and Firefox (about 68% slower).
I decided to ran the test on a Windows machine. While I could not run Safari on Windows, I ran the benchmark in recent stable versions of Chrome, Firefox and Microsoft Edge.
Chrome managed to get a score of about 105, Firefox a score of 78 in the benchmark. Firefox Nightly got an Infinity score instead which suggests that something broke while the test was running. The test did not complete in Microsoft Edge and I had to stop it as it would not even finish the first test of the benchmark suite.
Closing Words
The new benchmark suggests that Mozilla has some work to do to close the performance gap according to the benchmark. Benchmarks don't necessarily relate to real-world performance though.
Now You: Did you run the benchmark? How did browsers installed on your device perform?


Doesn’t Windows 8 know that www. or http:// are passe ?
Well it is a bit difficulty to distinguish between name.com domains and files for instance.
I know a service made by google that is similar to Google bookmarks.

@Ashwin–Thankful you delighted my comment; who knows how many “gamers” would have disagreed!
@Martin
The comments section under this very article (3 comments) is identical to the comments section found under the following article:

Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.
Omg a badge!!!
Some tangible reward lmao.
It sucks that redditors are going to love the fuck out of it too.
With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.
This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)
Almost al unlmited services have a real limit.
And this comment is written on the dropbox article from August 25, 2023.

For the God’s sake, fix the comments soon please! :[
Yes. Please. Fix the comments.
With Google Chrome, it’s only been 1,500 for some time now.
Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.
The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.
If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.
And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
