Are there any solid benchmarck comparing JSC vs v8?

JSC has had a set of large metabenchmarks like JetStream2 for a while. We have been the fastest for a while but V8 is gaining, so the current advantage is significant but not earth shattering.

The last time V8 had their own benchmark, they retired it right after we beat them on it and made a post saying that benchmarks are bad because people cheat on them.

Around that time I stopped seeing google.com claim that I should switch to Chrome “because it’s faster”.

So basically JSC is fast enough to have made V8 ragequit benchmarking. Hope that answers your question!

> ragequit

I've increased my vocabulary today.

In topic: I always wondered why chrome stopped that marketing spiel.

I've always wished I could actually benefit from JSC without dropping a couple thousand dollars on a macbook and having to put up with the world's worst keyboard, because your browser team kicks ass :)

At least you're pressuring Mozilla and Google to step up their game on runtimes!

it's not Mac exclusive. WebKitGTK uses JSC too

JSC is barely ever mentioned in the v8 team. They gave up wanting to be benchmark kings in the interest of having decent performance in Android markets (low-end and high).

Comments around cheating are likely aimed at OEMS who ship Chrome derived browsers and spin up the clock frequency when they detect certain benchmarks are running. These look great in online reviews.

I found https://webkit.org/blog/8685/introducing-the-jetstream-2-ben..., with a graph at the end, but of course that is written by Webkit (JSC) developers. Then there is https://johnresig.com/blog/javascript-performance-rundown/ from 2008. https://www.railsmine.net/2017/12/browser-benchmark-safari-1... from 2017, similar results to the JetStream 2 post.
