JetStream is a JavaScript benchmark developed by Apple. We ran the latest version, 1.1.

For this benchmark, a higher number is better.

Chrome again set the bar high:

jetstream_chrome_september_2015

Firefox couldn’t keep up:

jetstream_firefox_september_2015

Edge definitely could:

jetstream_edge_september_2015

Looks like Microsoft knows best how to blow through Apple’s benchmark.
