Disclosure: I work at Intel and submitted the post.

Dormando mentions the test was done with the help of Accelerate With Optane, a collaboration we have with Packet to provide access to servers with Intel Optane SSDs. Check out https://www.acceleratewithoptane.com/ for more info, and you can find me and the Packet team over at slack.packet.net. We're especially interested in open source projects that want to test what they can do with the tech and are interested in sharing what they learned with the broader community. Thanks to Dormando for going first!
