[Randell Jesup [:jesup] (needinfo me)]

Can someone post the detailed numbers for Firefox, Safari, and chrome on the same machine? (and preferably a recent macos; mine is still on 10.11, so I don't trust the numbers, and async-fs won't even work in Safari).

My look against Safari 11.1.2 (current is IIRC 12.1) had us winning on wasm and crypto, losing badly on a lot of other tests.

Obviously this hits ION very hard....

I filed bugs for some of the obvious issues. I didn't run all tests because there are so many, I just ran some of the interesting subtests.

To download the source:

svn checkout https://github.com/WebKit/webkit/trunk/Websites/browserbench.org/JetStream2.0

In JetStreamDriver.js you can enable particular subtests (search for if (false)).

To run the cli.js version, add this to cli.js:

runString = function() {
    var g = newGlobal();
    g.loadString = g.evaluate;
    return g;
};
readFile = os.file.readFile;

Should there also be a bug open for getting Jetstream2 added to automation (raptor harnessed?)

Yes, can you file one against PI?
