I prefer applications that you download and run on your local machine, but I guess I'm old-fashioned because it seems like even most of those run in a browser these days. Browser performance on a lot of computers now is virtually synonymous with whole-machine performance. For that reason, we pay pretty close attention to browser benchmarks. Tests like Speedometer and JetStream help us gauge how quickly a machine can complete internet tasks—which is to say, most tasks. Not to belabor the point. In any case, we're pleased to see that the JetStream benchmark has gotten its second release.
If you're somehow not familiar with it already, JetStream is a browser benchmark published by the WebKit guys. You know, the guys behind the package that powers basically every browser now. It came out in 2014 and was the first browser benchmark to weight latency and throughput benchmarks equally. JetStream is an intensive test and isn't representative of simplistic websites. Instead, it's intended to measure the performance of a browser (and the machine it's running on) in "advanced web applications" such as games, and things like Slack.
