Ask HN: Jest is so slow. Why Jest?

I've been running some performance comparison of different JavaScript test runners [1]. Jest comes out woefully behind everything else. To me personally that's a show stopper. However, Jest is popular and so I am clearly missing something. Looking through Github issues, it's also clear that addressing performance is not a priority. What is the priority? Who is Jest appealing to?

I'd really love to hear from people who, given a green light on tech choices, would pick Jest over, say, mocha or tape for their next project. Thank you!
